Tag group question

I'm looking through the tag group and trying to see where I can put the heptagram tag. I didn't see any shapes group, and nothing else I noticed seemed to fit. Any suggestions for this and future shapes?

Initially, I'd go with tag group:symbols. It does have star, at least.

Sounds good. I'm also adding pentagram, hexagram, octagram and decagram - plus enneagram for reference's sake - as geometric shapes.
