Multiple XP Tracks

New Feature Request

I have recently run a campaign here "The Age of Mystery".

I started with 5th Edition D&D Playtest & 4e D&D.

So I am using multiple XP Tracks for two consecutive games running in the same campaign.

I would like if the XP List of characters could group by XP Track, for example

Awesome XP Track #1 D&D Playtest Next
- Character A
- Character B
- Character ect...

Awesome XP Track #2 D&D4e
- Character A
- Character B
- Character ect...

Thank you.
