Drawings to Camera Roll

I would like to request a “save to camera roll” option for drawings.

I regularly use my phone or ipad to view build drawings in lieu of printed paper. I also share drawing with other in the shop the same way. This is, of course, not for overly complex drawings but for simple things. It would save the awkward screenshot and crop work around.

Maybe I am missing the point, but if you export an image of your drawing it will end up in the camera roll.
