Bespoke Map Card Regions

Sally

Is there any way to create a map card using bespoke regions rather than the predefined lists e.g. UK counties?  We work with our own definition of regions so each store is assigned to a region, however those regions don't align to counties.  I'd like to be able to use a map card with our own definition of regions - is that possible?

Thanks for the quick reply Anton - that's what I thought but it was worth asking the question to see if anything had changed!
