Leslie does something very similar. Adam has simply come up with a slight variation. Reviewing the files BEFORE they are imported seems like a good alternative to try. If I didn't use FAP, I think I would use that method as well.
Adobe, and other 3rd party versions of Acrobat, allow many ways to document on the files. If one uses the doctrine that staff who make less money than the provider should do the things they can, then it makes sense for your staff to do the busy work, i.e. importing and other things, while we are in the rooms making money.
I know that Leslie uses Paperport, and I just helped a colleague of Adam's and mine set up a Brother MFP. Most of the more expensive Brother MFP's come with Paperport, which allows you to mark up files and work with them easily.
