Provide additional flexibility to Bluebeam studio sessions. It would be great to, as the creator of the session, be able to drop the drawing down to my local drive, make modifications then re-upload with every contributors markup ownership retained/synced to the person who has marked up the session. Example, I forgot to add a couple of layers for a different service, download the original (maintaining ownership of others previous markings) add a couple more layers and re-upload this drawing. If the markup ownership can be maintained then business as usual studio session continues. At present, when it is uploaded, only I can edit the markups as the ownership is not maintained. In my opinion this is a real flaw in an otherwise great component of BB.
