I'd like to see the performance of different sales regions across the United States. We group the regions by state (i.e. Southwest = AZ, NM, TX) and it would be very helpful if I could define those states as a region so that when a user hovers over the card, they're able to see stats for specific regions rather than each individual state. Not sure how this can be done currently and any help would be immensily appreciated. Thank you.
