I want to designate a frame as an overlay so that when I create an interaction pointing to it,  the default action is “Open overlay”.  If I create an interaction from an overlay type frame, the action should default to “Swap overlay”.

For example.

1. I create a frame called “button”
2. I create a frame called “pop-up”
3. I set “pop-up” as an overlay type
4. I create a prototype connection from “button” to “pop-up”
5. the iteraction defaults to “Open overlay”.

Figma’s UI already identifies overlays with an icon but this doesn’t happen until a connection is made to a frame and then the action must be manually set to “Open overlay”. Enven so, if a connection is made to a known overlay, the default action remains as “Navigate to”, which is not the desired behavior.
