Sorting of Playlists in "add song to playlist" and "export playlists" mode

Hi there I have a little question about the playlists.
I know that there is no way to automatically sort your playlists in any order so I do that manually.
But when I want to add a song to an existing playlist by clicking the right mouse button, the sorting of the existing playlists are in the order in which I created them in the first place. The same problem exists when I try to use the "export playlist" plugin.

So my question is if there's a way to sort the playlists in those modes?
