Add icon/pin to map

Hello,

I am able to add buttons and read/write to files. I can also send vehicle info to those files. I am using QT creator and the custom example from Github. I added the buttons and the read/writing in the CustomFlyViewOverly.qml. I am generating simulated vehicle data using Gazebo. i can also add a PX4 mocklink as well

I was wondering how to add multiple pins/icons to the map?

as well as how to switch the active vehicle?

thank you,

Jon
