It would be nice to implement a tool in Revit for creating mulitple sheets automaticcaly by one click.
There's Dynamo for that, and for this purpose solely Dynamo is super easy
Check the Revit app store. Lots of sheet-related apps...
You can also set up placeholder sheets in your template. They are a "one-and-done" option, but they work well.
My company created a plugin for exactly that purpose
I hope you may find use in it, here's the link:
