Multiple users and shared folders

Is there a way to have two users in the same acrobat dc account, so that one user can share certain folders with another user?

The situation is that my boss has an acrobat dc pro account.  I created a free account that we would both log into at different times.  It is for processing bills.  I put the bills in the cloud, stamp them received, and code them.

Then my boss later goes into the same acrobat dc account and puts his notes on the bills and approves them.

But, on his pc, since he has his other acrobat account, it is inconvienent for him to sign out of his account and into the free account and then back again.

I'm wondering with his pro license, or maybe an additional license for his pro account, would we be able to just use that one account, where he would make the folders for the bills and share only those folders with me, since he'd still have all his other work files that I wouldn't want access to?
