Glad to see I am not alone with this problem in 2019. I can't believe we cannot reclassify these auto-matched transactions in batch. The only two batch actions in 2016 QuickBooks for these are "Add/Approve & Ignore", but both of these will get rid of the transactions! QuickBooks really needs to fix this because as many have said before me, it is a huge inconvenience to go through each individual transaction and click "Not a match".
