When you create one of the reports grouped by payee, Quicken displays a Choose Payee button that you can click to select different payees to display in the report. Clicking this button opens the Payee tab of the Customize dialog which, by default, displays the payees used in the transactions for the last three years. If the payee you want isn't in the list, at the top of the Customize dialog, in the Date range field, select a date range that covers more than three years. Then try searching the list in the Payee tab again.
Thus the payee list defaults to all the payees for the past 3 years. You can search the list by typing the beginning few letters of the payee you are looking for in the box above the list. You can repeat this process to find and select multiple payees. You can also do a "Contains" search for payees in the "Matching" section at the right.
