Sign a pdf without flattening layers
I have a pdf with two (or more) layers, let's say they are for different language versions of the same document. I want to send those for review, approval and signing to a group of people. When I do that today using Acrobat Pro DC -> E-Sign -> Request Signatures, the document is flattened before the reviewers get to see it. I'd like for them to be able to select layers and approve and sign once they've checked them all.
