download all owned set instructions as pdf

I tend to build from pdfs on my ipad as it often helps with build space and also colour differentiation by zooming in. I was trying to keep up with downloading pdfs when I buy sets but I’ve lost track now.

is there any way to do this in bulk - eg get a list of all sets I’ve scanned into lego insiders, or that are on rebrickable - and download pdfs from there? I’d really prefer to avoid doing it all one by one as the instructions are partly in storage so rebrickable is probably the best source of my current collection (and even that needs an update)
