Creating a summary credit invoice

We are on PeopleSoft Billing 9.2

We are onboarding a legacy business to PeopleSoft using file based approach. i.e. we'll be receiving the data from legacy in csv files and by reading the data in the files we are going to create invoices in PeopleSoft

We have monthly statement customers for this business and they want to receive a consolidated invoice (be it a regular invoice or a credit invoice) in a month. In the current scenario, we need to generate a single credit memo for multiple original invoices of that customer and send that summary credit memo to the customer only once in a month. Is there a way in Billing to achieve this ?
