When setting tool tips for a radio button in acrobat, it only allows one tool tip for the entire group. When the PDF is displayed as an "image", as it is in some implementations, a screen reader cannot help someone choose which option to select.

I use text tagging in Acrobat to upload to Adobe Sign. I have to manually adjust every radio button after I upload it because Acrobat does not support unique tool tips per radio option (but Adobe Sign does). This makes the process MUCH more laborious when I could just simply upload it and be done.
