Feature Request: Album cover selection for higher up the album tree

You can't make a photo the "album cover" for other than the album you're in, but not levels above. G2 allows selecting a higher level in the gallery's structure to apply the "album cover" to (names are different is G2, but the function exists). floridave suggested this might make a good module.

Thank you. I hope this is the right place to post. I couldn't find any other location to place a request.
