[Map card] Option to collapse all device_trackers of a single Person into the person marker

[danstis]

The built-in Map card shows every device_tracker.* entity, so each family member appears multiple times if they carry more than one device (phone, watch, car GPS, etc.). Home Assistance already has people objects and I have created people and bound the device trackers, but I still see each tracker on the map card.
I would like an option on the map card to consolidate all bound trackers with a people object into a single map item, with the last update wins (or similar).

As an example, these 2 devices are both bound to the same person:

I'm fairly sure this is a feature request, as I can't seem to find any method to do this today, without manually selecting entities for teh map card. I would prefer to have the entities that are displayed dynamically updated, so I capture all new zones and device trackers automatically.
