1099 misc & nec

Hi, I have Quickbooks Desktop Pro 2019, and I do not have the Accountant Tool. I accidentally mapped all of my 1099 accounts to NEC Box 1 while efiling my 1099 forms NEC without seeing QBs new instructions on how to map different accounts for NEC and MISC. So now that I am attempting to efile my MISC 1099s, I see when i get to #3 where you Map Accounts I cannot change my accounts from NEC to MISC where it says "Apply Payments to this 1099 box." I first read QB forums hoping I could reverse the action where I accidentally mapped all of my accounts to NEC, but I'm not seeing that as a possibility. If it is that would be the easiest solution. If not, the QB forums say I need to create new accounts and move the transactions to file both NEC and MISC separately. I've created the new accounts already and mapped them under MISC, but now I'll have to move thousands of individual transactions from NEC to MISC so i can file the MISC 1099s. So 2nd question, Is there a way to bulk move all transactions under a Vendor from the NEC accounts they are currently listed under to the new MISC accounts I've created so I dont have to click on each individual transaction? I have seen forums where people bulk move items under Accountant tool, but I do not have that feature. Can I do it without the Accountant tool?
