This a great article for the process even if you don't have a RM2 so great hack to solve your own problem. I have been achieving something similar on my home PC setup using tldraw [1] which is a live multiplayer infinite canvas board service that I also join from a surface laptop with a stylus. I share that tab with others in a call from my PC and dump in its screen shots etc that I can markup from the surface tablet or anyone can join the tldraw session when it makes sense. Anyway its a web service not your own, you don't have the RE2 OCR and filing system or eink etc and there are a lot of other infinite canvas solution to choose from, but it's working and turned out to be simple enough for me to use more than once lol.
