MyGallery: subsubfolder

Hiya!

MyGallery works great, thanks to the developer(s). I need to create a photogallery with subsubfolders, that is:
myphotos
|
--> 2004 --> (several folders)
|
--> 2005 --> (several folders)
|
--> 2006 --> (several folders)

and so on. That, is, ‘2004’, ‘2005’, ‘2006’ are subfolders of ‘myphotos’ (where there is the tag [mygallistgal]). 2004, 2005, 2006 don’t contain any picture themselves, but just the list of subfolders where the pictures are. Is it possible to do that? Cheers in advance
