I was going back and forth with Adam telling him I though that more people would use PI if the calibration process was easier than it was, and he kept telling me that it was. It kept assigning darks to the wrong lights or my flats wouldn't work and just couldn't get it too work. Manually worked fine. After all the back and forth this import process was the only missing piece I needed to know and BINGO - it was easier than I was suggesting it should be to him.
Create these Folders in a parent folder (Unique first word that cannot be found in any filename or folder within the parent folder. UNDERSCORE something different for each, doesn't matter)
BodeHood_SetA (add all darks, lights, flats and dark flats for this set)
BodeHood_SetB (add all darks, lights, flats and dark flats for this set)
BodeHood_SetC (add all darks, lights, flats and dark flats for this set)
In WBPP add BodeHood or whatever the first word of all those folders is under Grouping KWs and add it.

Then click the Directory button at the bottom of any of the tabs on the left and select the parent folder from above. Your files should then import and be grouped properly.

Check everything is hunky dory and change the Exposure tolerance on the post Calibration tab to 500, and leave it there. Having
