Adding Rows to a sheet index

Is there a way to utilize Dynamo to ‘Add Rows’ to the sheet index? I’ve seen the question asked before but it’s always shot down as something that should be done by the creation of dummy sheets, which is not ideal for the way we operate.

We always add dummy rows to our live architectural sheet index to pick up MEP and other disciplines. How do we do this in Dynamo?

This function seems to be exposed in the API.

BINGO. Thanks!

Does anybody know if it is possible to determine in a sheet index if a sheet is a placeholder or not? In other words, if I wanted to clear out all placeholder sheets without deleting the actual drawing documents?

Thanks again!

Great. Thanks!
