How do I create a custom renaming rule?

The Create Custom Renaming Rule dialog gives you a bit more control over what constitutes a renaming rule "match" when a payee is downloaded.

At the top of the dialog you'll find the payee name, exactly as it was downloaded by your financial institution. Just below that name is a field containing the different elements of that name.

Create a custom renaming rule from a transaction

In the rectangular field, click the elements of the payee name that you want Quicken to scan for in downloaded transactions. These elements can be words, abbreviations, numbers, or symbols. A transaction must contain all of the selected elements before Quicken qualifies is as a match.
Enter the standardized name that you want to use for the payee.
Click OK.
