The only way to do this using Premiere Pro is to do it twice. Record the VHS tapes to MiniDV , then capture the MiniDV.
Otherwise, you'll have to babysit.
While there can be reasons to leave, I use that time to observe the VHS tapes, and write notes on each Capture. By the time that it finishes, I have a spreadsheet with all of the necessary details on that Clip, and much of my editing has been done in my head. When the Capture is complete, I just sit with my notes, and make the required edits.
As Jim points out, one needs to have Device Control, to log Capture to specific times, and a VHS deck does not allow for Device Control, where a miniDV tape deck, or camera, should provide that function.
When I was capturing my ton of vhs tapes I used SCLive, which has a start/stop timer and a capture duration timer. I think it's still available.
