Mobile: Import PDF in "Draw picture..." mode

Hi there,
I'm currently trying to replace GoodNotes with Joplin and there is only one feature that is missing to make it possible: Annotating PDFs with a pen.
I already like the "Draw picture..." mode a lot and I've seen that there already is an image import option in this mode. Would it be possible to also import PDFs in this way and thus annotate them with a pen?


I really like this suggestion!

The difficulty I was having with PDF annotation was saving the annotations as part of the PDF. This would be much easier to implement.
