It would be nice to have a way to bulk add multiple GSC properties. It could be structured like a process queue, it doesn't have to work as an async method (which would be great of course, but i suppose it make the writing process on the local database much more complex). In particular during the onboarding phase it's very time consuming to add and wait. If i know that the systems has queued 10 properties i could do something else for an hour.
