Can we group legends with number in Power BI map visual

[Anonymous]

I have a requirement to group the Map visual with its total number, like for example if we have number of countries mapped are 6 then in first place at higher level we need to show 6 as it number and then when we click on the number 6 it should show those 6 countries information. 

So is it posible to show the total number of sources/countries on map at first level.

I have attached the screenshot of UX design for your reference. 

Thank you
