Suggested feature: Linked map flag in addtional to personal a flag

I don’t know how hard this would be to implement but a lot of times if I’m doing maps I’ll scout out my map location and mark it with a flag but sometimes I’ll click on someone else’s linked cordinates and loose my flag, is there anyway for the devs to maybe make it so coordinates linked by other players creates a second flag?

That should have been in addition to a personal flag =/ sorry phone posting

There's a group of people I know that would appreciate the hell out of this.

Would love this for map parties.
