The new Renaming Rule setup dialog introduced in R62.14 is generally an improvement.
However I ran into a problem trying to add a new rule for an an existing Payee name. To add a rule before this change, you would click on the green plus sign next to the Payee name and enter the new rule. Now if you click on the plus sign, you can enter the new rule but then you are stuck - the only option is Cancel. Note that the Rename the downloaded payee to: box and the OK button are grayed out.
Apparently the new way to add a rule for an existing Payee is to click on Add a Rule at the bottom of the list and then select the Payee from the dropdown list.
The new way works and seems logical, but clicking on the plus sign next to the payee should either be fixed to work as it did previously or the plus sign should be removed.
