Our development officers frequently ask for a layered map of different categories of donors, and it is very common for donors to be in more than one category/research list that is used as different Groups on the map. For instance, a major donor can also be a recurring donor, or a planned giving prospect. But current functionality for maps does not show when there is cross-over between these Groups. This would be INFINITELY useful to have the Map identify these pockets of synergy when looking at specific layers of our donor base.
