Wasn’t very sure how to describe this one, see GIF below. This is functionality that I just created similarly in another app. I thought it was a pretty good setup so I thought I’d share it.

Take note of the Format Rules, the three Actions, one Slice, and of course the Table/Column configurations.
Hope this idea is useful for others, or that it inspires some other related Appsheet creativity.
