[Dolphin] Using a main/global memory card for all Gamecube games?

Good day. Is there a way in which I can use a main or a global memory card for all of the Gamecube games I use through Dolphin? As far as I know, Dolphin creates only one .raw file per-game, but I’d like to know if I can have only one .raw file for ALL the games.

Something similar to what the Nintendont homebrew app on the Wii does, in which you can setup a main memory card of a set filesize called “ninmem.raw”, and use that one for all the games.

Thanks in advance!
