Add details to groups

I am currently using to track our company’s licensing in various states. As we have about 14 different states we need to track applications / action items for I wanted to keep this all in one board and have each state be a different group.

However there are some individual details I want to add about each group and there doesn’t seem to be a place to keep that. Ideally would love to be able to add descriptions for the board as a whole, and on each group level if needed.
