No automated way, but you can make things a lot faster with a script of mine. The most time-consuming part of the process isn't the crop, but saving the file and opening the next... Which is what my ofn-file-next script does. You can assign it to a key, then:

1. Open the first file normally (File > Open...)
   
2. Crop it (Click, drag, Enter)
   
3. Strike the key defined above to save the file and open the next in sequence, and you're ready for step 2) on the next file
   
4. Rinse and repeat
   

I used to have to crop a good hundred receipts every 6 month, and this was very handy, you can crop a file in under 2 seconds.
