How do I change revision numbers on sheets with dynamo rather than schedules?

I generally change the revision number on my sheets by creating a sheet schedule and having to change it individually within the sheet schedule.

Is there any way I can create a script that can bulk change the revision number on sheets?

hi ,
there is Nodes to add & remove revision in archi-lab package

Revision manager makes those changes. Just add a revision schedule to the title block family and the change is universal.
