Mapping color to dimension selections

[#1]

I have a Retail solution which has google maps as an object. Each bubble is a Retail branch outlet. Branches can be subdivided into Regions. My question is...How do i change the colors so that branches are color coded according to the divisions, instead of random colors being assigned by default as colors 1-6, colors 7-12 etc?

In the properties of expressions.
You can make a conditional

Like this

You have a solution using 2 dimensions instead of one

first one is Outlet

Second one is Regions
