Ocarina: Using multiple RSBE01.gct files for Brawl mods with USB Loader GX or WiiFlow

[manymods]

Is it possible to play Brawl mods by loading different RSBE01.gct files with USB Loader GX or Wiiflow?

In USB Loader GX or WiiFlow, is there a way to select which RSBE01.gct to use for Ocarina?

Can you create multiple game profiles/settings for Brawl mods?

Thanks in advance.
