Defining Custom Layers in Maps

Hi There,

We are looking for a layered map approach in Power BI, According to Our requirement, we need multiple custom layers which we can define with data(longitude, Latitude, Pin/zip codes) for one main layer which shows Heatmap and above the Heatmap we want to see the Dots/Bubbles(Zip codes will be the data) which we will be giving as a input. Could Any map will fulfill this requirement and Is there a limitation with number of records?

Thanks In advance for the help.
