Is it possible to replay Akka Persistence Journal on all Actors?

I have an Akka Persistence Journal and several databases serving different views on the data saved in the journal. Most of the views include multiple entities ( -> multiple Persistent Actors ).

I understand that I can trigger recovery for one actor, which would rebuild the views consisting of only that entity, but in case I want to rebuild all views, how would I go about this?

I could startup all existing actors (for which I would need to know all of them) to trigger recovery of the whole system, but is there a way to give a Journal to an Actor System and basically tell it to replay the whole thing?

With Akka Persistence Query you can do

readJournal.allPersistenceIds()

and start up all actors using the persistence ids, which would trigger recovery..
