Payment Automation Set-up for Remaining Balance Due

Is it possible, and if so how, to set up a payment rule that automates the charging of a remaining balance due on the morning of a reservation’s arrival/start date?

At the time of booking through the booking engine on our website, we collect payment for the first night’s room/tax plus any add-ons included during the booking/confirmation process. For multi-night reservations, the remaining balance is comprised of room/tax for nights 2 and beyond. I have not been able to figure out how to do set up a settlement rule. My first rule collects 100% of the first night plus additional expenses an products. When I attempt to create a second rule, I get an error message advising me “The sum of settlement values from all settlement rules with ‘Charge payment card’ action related to the parent rate group with ID… cannot be more than 100%”. Makes sense, but he only other option is a flat amount.
