Transition to AP Batch

Dear Team

We are not using the AP invoice batch at present. We are planning to use the AP Invoice batch functionality in near future. Due to some business requirement, business is planning to pay the invoices based on the AP Invoice batch, i.e. they will select the Invoice Batch name in Payment Manager.

Can anyone please let me know how to handle the invoices which are entered prior to enabling Invoice Batch? Is there any way to bring them under AP batch, so that user can select that batch name and make payment?

Thanks & regards
