Restrict area to pick?

[martin-braun]

I know that I can make checks after an address was picked, but is there a way to show an area circle on the map at a specific coordinate and a specific radius and allow to pick only addresses in that area?

Use case is to show a delivery area of a shop and the user enters his address to which the user wants to get the food delivered. Any attempt to enter an address outside of the circle area should fail right away.

Is this possible?
