It would be nice to be able to merge two transfer transactions with same date, opposite account and amount such that they don't show up as manually entered.
Use case:
I have numerous debit "Transfer:Credit Card Payment" entries in my primary account, which are not linked to any particular CC. My various CC accounts have same-amount/day credits that are not linked to my main account.
While trying to clean this up, I wholesale selected these transactions and applied the new category. Sadly, this seemingly circumvents the matching algorithm and created new transactions in the target account. Now everything is duplicated. And then quicken adds Adjustment transactions. The noise in my various registers is overwhelming.
