No this isn't possible. The renaming rules and memorized payees work hand in hand. Quicken matches the downloaded payee to a memorized payee and uses that payee entry to fill in the category. The payee in the transaction and the memorized payees have to match exactly, except for case. That is the main reason for the renaming rules, to "normalized" the downloaded payee name so that it will match a memorized payee.
What you would have to do is use a renaming rule for the person, and have a memorized payee for that name that has the category you want.
How about you try this? Record the Rent Payment transaction using the Rent Center. This posts a properly named and categorized transaction into your Checking account. When a download comes in with a Zelle deposit from one of your renters just match the already existing rent transaction to the downloaded Zelle transaction. No renaming or recategorizing necessary.
