Hacking Custom GBA frame images for individual games?

[Sora de Eclaune]

I'm using Wood R4 and realized that all of my GBA games have unused space in the DS's screen, and would like to get a GBA frame image. However, I don't want to use a generic one for all of them and would rather have something similar to GBC borders that are unique to each game.

Does Wood R4 support custom GBA frame images for individual games? (i.e. something like "gba_game_frame.bmp" and "gba_game2_frame.bmp", with the first only being seen when playing game.gba and the second only being seen when playing game2.gba)
