OnMarkerTitleClick-Event in TMapView, (alternatively CustomMarker)

Hi, Im wondering if anyone has successfully added a clickevent to a TMapMarker title, the popup that is shown once a marker is clicked?

I need this because the user should be able to click on a marker, get information (title, snippet) from that marker, and then decide (by clicking on the popup) whether or not to show more information about this marker in a new window.

Im also interested in some sort of CustomMarker, to be able to show a picture, or more text. This would also solve my issue.

I am using:

RAD Studio 10 Berlin

Firemonkey Multi-Device-Application with a TMapView

Thanks a bunch in advance!
