RB3 PS3 folders convert to CONs - multiple versions of the same song overwrite each other?

[amenoko]

Hey, I'm trying to convert the customs I have on my PS3 back to CON files so I can convert them into Clone Hero compatible folders. I'm using the "RB quick convert + pack creator" menu but if a DLC folder has multiple versions of the same song (for example same artist and song title but different charter) then it will not export all songs, I assume because the multiple versions overwrite each other. I tried entering %song_id% and %author% into the filename field (because they're available in other menus), but for this menu they don't work, it just literally puts "%song_id% or "%author%" into the output filenames. Is there a way around that? If not then I'd like to request the template feature in this menu as well.
