We finally upgraded our Bartender about 30 versions to Bartender 2022. All of the labels we print (about 8100 files over the last 15 years) open just fine in BT2022 but all the Page Setup -> Page Sizes are wrong. We use 3 standard labels and setting a default page size doesn't seem to work in the printer settings. I'd love to be able to write a .py script that can change the .btw file metadata. Does anyone know if the page size/page layout is saved in the file and is editable without opening BT?

When I open a .btw file in notepad++ it has a few bits of readable text but nothing I can decipher as page size data.

Any input to this would be grand and save me tons of time.
