Retroarch Playlist Rom-Path

Hi, sorry if this is a dumb question.

I use Retroarch on a pendrive so i can plug and play everywhere and anytime I want, but the problem is… Inside the playlist there is a rom path using H: from my computer and when I plug it in another computer the driver letter changes and because of that retroarch can’t load any rom from the playlist because is set to H: in there.

Is that a way i can make the “rompath” inside the playlist change automatically? For example, using emulationstation I use %home% or ~/ so the driver letter doesn’t matter making “.emulationstation” the home folder, making it portable. It is possible with the retroarch playlist?
