Debug Draw behavior in editor

I have a linked object which is a spawn area manager, that has an area of spawn points associated with it. Both the manager and the points are separate actors, and as such can be given an editor representation to make it easy for a level designer to play with it.

What I’d like to do though, is link these objects with a line in the editor, so if a manager is connected to a point far away, it is easy to spot. I can do this trivially while the game is running via the Debug functions, but since there is no Tick() in the editor, the usual approaches for this won’t work.

Suggestions?

C++ has Tick In Editor.
Not sure if there is a Blueprint equivalent.
