pause a transfer

Came across your software as I couldn't seem to find a solution for the feature I'd like.  Sometime i need to move large amounts files.  Some individual files 2-3TB in size (Final Cut Pro project packages) which can take hours.   It would would be great feature to be able to pause a transfer if for whatever reason you need to shutdown, and then pickup from where you left off.  Or if for some reason the computer shutdowns unintentionaly, be able to do the same and verify all was transferred completely.
