PowerBI Azure Map Visual - Add Multiple Reference Layers with end user toggle ability

The new reference layer functionality is fantastic and I would like to request the ability to layer multiple and allow the end user to toggle/filter which ones they want to see on the map. In the current state, it is an all or nothing approach where several shape file layers can be added to one and display all layers at one time. For example, adding multiple reference layer functionality would allow for the ability to add multiple underground utility layers such as electric, gas, water lines, etc
