Is there a way to get all tagged objects on map?

Hello,
I need to get all tagged objectson map to store information about them in a save file, is there an easy way to do it or do I need to add them manually?

Get All Actors of Class : Object → For Each Loop → Actor Has Tag? (True) → Do Something about that actor

If you are talking about objects not actors, sorry there is no way to get all objects easily
