I have a copy of my course roster in a Miro board. It is a PDF. I’d like to be able to edit that doc with pen etc., and immediately have that markup locked to the board. I’m assuming that I have to using the grouping feature,  and perhaps locking? I’d love to be able to make those edits quickly (e.g., in front of the class) without having to remember to lock them all in place. I learned this the hard way. I made careful notes on the first day, and forgot to lock them down. I later resized/moved the PDF, and as a result I now have pen marks that do not match up with document. Had I noticed immediately, I could have just used Ctrl-Z, but I didn’t… I’m hopeful there’s a simple feature that lets one mark up and make the edits essentially burn into the PDF, so no amount of resizing/moving leaves the edits stranded.
