fic* in a box!

I have a doubt. I have nominated a couple character relationships on the Google form from a fandom that was in last year's exchange. It's Critical Role - Web Series. But since there are new campaigns that launched this year that are obviously not in last year's tagset, how should I proceed with that? Do I nominate directly on this year's tagset? Sorry if this is a bit confusing, I was waiting for the nomination guidelines to come through to nominate!
