Selecting Gallery item based on Selected Geospatial Map Item

[TobiasSQA]

Hello there

I have an app where I'm using the Geospatial Map component, I'm using a popup to show information on the pins (the pins come from a sharepoint list), when this information is shown, the user also needs to be able to navigate to an Edit form screen, this would edit the item that the user selected on the map. 

How would I go about selecting a gallery item based on the selected item on Geospatial Map Component?

I have attached two screenshots of the relevant screens, #1 is the map with an item(pin) selected, #2 is the form where you'd edit the customers information

All of this information comes from the same Sharepoint List, and are all Edited via a Form and Selected via a Gallery.

Thanks in Advance
Tobias
