Karend yes you can with ProSeries professional software. If I am correct, you and I both use ProSeries 2017 and Windows operating system. Because the process to complete the transfer and update of the accepted Extension is a bit long, I have attached a pdf of the process to hopefully prevent any issues you may run in to. It took our firm several hours to perfect the process in the correct order but if done correctly it should take you less than 30 minutes to complete the process even on your first try. Hope it works for you as well as it has us. Good Luck and let me know if you need anything clarified. I attached the instructions in both Word and PDF formats in the event you may want to add your own notes.
