Custom Group of States Filter

Custom Group of States Filter

Newbie here to Analytics. I've built a basic dashboard that gives us a good amount of what we need for a project, but I'm struggling with something that I'm not sure is possible.

We have reps who handle groups of states and I'd like to create a custom filter for each of these groups that filters the Dashboard data to the relevant data.

For Example:
Group 1: NY, CA, TX, FL
Group 2: NC, GA, MI, OH

I'd like to create a filter labeled `Division` that has options of Group 1, Group 2, etc which updates the dashboard for only that divisions data.

Is this possible?
