Remarkable

Hi, Does anyone have a solution for this problem: I use the remarkable to view sheet music. I also take extensive notes during practice. I would ideally like to just point the device at a folder on my NAS and have it sync once connected to my home wifi, in both directions (new pdfs from the NAS get copied to the RM, notes taken during practice get copied to the NAS). If there is no solution for that, maybe I could use a PC as a sort of "middle man" and sync it when the RM gets connected to the PC? If that doesn't work either, can this maybe be done via the dropbox intergration? Obviously I need to install additional software, at least for solutions 1&2. I'm not scared of the command line, so any solutions involving that and maybe even a bit of bash scripting are totally welcome.
