Yes, I think I mentioned a similar solution in one of my latest posts.

It's probably missed in the long discussion.
 

One nitpick that's not a big thing and I'm not sure if anything can be done about it: In the folder view, the alternate versions and extras are intermingled in the list.  Is there a way that those can be made to force the versions at the top of the list?  I can sort by duration and that does it most of the time, but not necessarily always.

In fact, Kodi core does return them with versions at first, extras at last. The problem is skin will apply sorting on the list, which will sort the items. It's out of the control of this feature. It's better to request this in the skin section for each skin to treat the version folder specially on sorting.
