ag.algebraic geometry - extending local modules to global modules

Let $X$ be a scheme and $x in X$. Consider the functor

$text{Qcoh}(X) to mathcal{O}_{X,x} text{-Mod} , M mapsto M_x.$

Does it have a right-inverse? I.e. is there, for every $mathcal{O}_{X,x}$-module $N$ a (functorial) quasi-coherent $mathcal{O}_X$-module $M$ such that there is a natural isomorphism $M_x cong N$?

If $X$ is quasi-separated, the answer is yes. First observe that, if $X$ is affine, the direct image with respect to $text{Spec}(mathcal{O}_{X,x}) to X$ works. Now if $X$ is quasi-separated, use the affine case to extend $N$ to a quasi-coherent module on an open affine neighborhood $U$ of $x$, and then take the direct image with respect to $U to X$. This works since $U to X$ is a quasi-compact, quasi-separated morphism.

In the general case, note that direct images don't work, but this does not disprove the existence of the functor I'm looking for. The question is motivated by this one, which is still unsolved.

If $mathfrak{m}_x subseteq text{rad}(text{Ann}(N))$, then the direct image with respect to $text{Spec}(mathcal{O}_{X,x}/text{Ann}(N)) to X$ (this is then an affine morphism!) works.

EDIT: A stronger, but more natural question is the following: Let $U subseteq X$ an open subset. Does then $res : text{Qcoh}(X) to text{Qcoh}(U)$ have a right inverse? As I said, this is clear if $U to X$ is a quasi-compact morphism. In general, a transfinite recursion on the length of an affine cover shows that it is enough to consider the case that $X$ is affine, but $U subseteq X$ arbitrary. Then everything is ok when $U$ is quasi-compact. In general, you can write $U$ as a directed union of quasi-compact subsets of $X$. Does this help somehow?

EDIT 2: There is a right adjoint $text{Qcoh}(U) to text{Qcoh}(X)$ to the restriction functor due to abstract reasons. If $X$ is affine, it maps $N$ to the module associated to $Gamma(U,N)$, where the latter is considered as a $Gamma(X,mathcal{O}_X)$-module. However, this fails to be an extension of $N$, i.e. the counit $widetilde{Gamma(U,N)}|_U to N$ is no isomorphism in general (I have an explicit counterexample). Thus, the desired right-inverse (if it exists) won't be a right adjoint.

EDIT 3: Here is a class of examples where extension works. Assume $X$ is affine and $U subseteq X$ open can be written as $coprod_{i in I} U_i$ with $U_i$ affine. If $M in text{Qcoh}(U)$ and $M_i := Gamma(U_i,M)$, then $widetilde{Gamma(U,M)} = widetilde{prod_{i in I} M_i} in text{Qcoh}(X)$ is not an extension of $M$, but $widetilde{bigoplus_{i in I} M_i}$ works.

EDIT 4: Let $U,X,M$ as in edit 3. Then an application of Zorn's lemma shows that $M$ can be extended to a maximal open subset $U subseteq V subseteq X$. Then for every open affine $W subseteq X$, either $V cap W = W$ or $V cap W$ is not quasi-compact. In particular, $V$ is ("very") dense. For example, $mathbb{A}^{infty} - {0} subseteq mathbb{A}^{infty}$ is such a dense subset. But I don't know if here extension works. I've already looked at several examples, but have not found out anything ..

EDIT 5: If $dim(X)=0$, then extension works.

Please let me know if you have any ideas!
