Using Import Tool to Process Document Revision Updates?

We use the Import Tool extensively to upload documents (mostly drawings) received in bulk from vendors.  To be clear, these are drawings that have never been in M-Files previously and have been reviewed and approved externally outside the M-Files process by vendors.  So the Import Tool works great because it allows me to enter the true Reviewed, Approved, and Released Dates via the CSV spreadsheet.

Now, however, I’m in receipt of dozens and dozens revised drawings have been reviewed and approved outside the M-Files process.  How do I modify the CSV so the Import Tool understands that I’m actually doing a bulk Revision 1 Update to these existing Rev 0 drawings?
