Display Points within a Distance Radius on a Power BI Map

I love this but I need a slight variation. I am trying to plot locations in reference to a different set of data points. This meets 90% of my requirements the only difference is I need to select from one set of locations to specify the reference point and the and plot locations from a different set for a certain area around that reference location. Any ideas how to accomplish that, or have you seen this done before.

It seems your solution is very close it looks like I just need a secondary table with locations and then to figure out how to connect the two so when you select the reference point it plots out the surrounding locations from the second larger table.
