Add Revisions to Multiple Sheets - Error

Two part question:
A. Is there a quicker way to get the script to write to multiple sheets or do you have to manually link each sheet number with Item0; item1; item2, etc?

B. I ran a script successfully to add revisions to multiple sheets. After running this script, closing dynamo and even closing and re-opening the model, I’m unable to manually uncheck any of these sheet revisions. The box is grayed out.
Any ideas?

Thank you
