Lease Integration to Payable use of Multiperiod Accounting

I am currently working on a Proof of Concept with the Lease Integration to Accounts Payables and noticed certain invoices using the Multiperiod Accounting fields and was hoping for some guidance as I continue my research, stepping through all journals created at each step of the process.

Specifically, I am concurrently working on Multiperiod Accounting based on PO data and have "disabled" (via Journal line rule) Payables usage of Multiperiod Dates at the invoice level (MPA only fires if MPA dates exist in the PO).

My question is will I have to redo my journal line rule to reenable MPA at the invoice level (and hopefully specifically for invoices from lease integration [source= ORA_FLA])?
