That response is typical from anyone associated with QuickBooks!  I don't mean to be rude, but it must be in the customer service training manual to: (1) offer a multistep work around that doesn't actually accomplish what the customer is asking for and (2) tell said customer to "recommend sending the feature request directly to our Product Development team" (where good ideas go to die).    

It really should be simple enough to have an "UNDO"  button where one click will undo what you just did.  Microsoft figured this functionality out 25+ years ago.
