Option to have alternative tracks (layered) on a playlist

I know there is the feature "Matching tracks"

But the thing is, let's say I want to prepare a dj set, but want to have alternatives right away to follow the mood of the dance floor.

So I with track 3 on master, but I'm not sure if for my track 4 I'll be wanting a deeper bass or funkier track. And I could have like 3 alternatives for track 4.
