Accounting changes based on event type (Advance and Retention) in Project billing

Summary:

we have requirement that advances and retention require separate account generation. We have created two different event types in Project Billing and transferred the invoices to AR as individual line items. However, how can we generate two different accounts if the advance and retention accounts are separate

We are sending three lines to AR (Invoice line, Advances, and Retention). We are currently checking the feasibility of generating different accounts based on event types from PPM. The business requirement is that Advances and Retention should be posted to separate accounts during invoice generation and accounting

I appreciate any insights, recommended setups, or documentation references!
