Lease accounting payments done directly in AP module with IMS integration how can we tie with leases

We are currently implementing lease accounting and need guidance on the approach for the following scenario:

Our client has "Berthing leases," which involve daily variable payments including base rent. At present, these payments are processed through a third-party system called IMS. In the future, the client intends for these payments to continue originating in IMS, but to be integrated with AP module so that invoices are created in Oracle and paid from there.

From a lease accounting perspective, we have already recorded these leases. However, we are unsure how to reconcile or link the payment details. Specifically, we are considering disabling the "Generate Invoices" field in the lease accounting module to prevent duplicate payments, since the lease accounting module can also generate invoices, but only with payment frequencies such as monthly, quarterly, semi-annually, or annually—there is no daily option.
