Hi Doug, I took a look and think I understand.
Would you let me know if this model doc here successfully displays the behavior you’re looking for?
It has two tables:
One, Document Master List is meant to be your “Inventory” that has all the documents already in your system.
The Other, Document Intake, is meant to be where you paste in (or somehow generate rows into) all the new documents you need to cross-check against the master list.
if the docs in Intake ARE in the master list (in this case, if there’s something else with the same name, although you could compare them another way), the checkbox is checked. If they’re not, the checkbox isn’t checked and a button is enabled that allows you to copy that row into the master list.
Let me know if i’m on track or not!
