WordTour: Many artists?

Hello,
Has anyone managed to extend WordTour plugin to mulit-artist events? Most of gigs would require that. There could be co-headlining show where would be better to present all artists.

I know that this might require new tables in db + many-to-many relations. But maybe someone’s already managed this 🙂
Thx in advance
