Configure revenue accounts based on events or revenue categories in PPM

Our Scenario:
For a specific grant project (e.g., UNICEF Pump Installation), the billing should generate a combined entry, but split the revenue portions dynamically:

• Main Project Revenue Portion: Should clear to a specific account (e.g., UNICEF Income CR).
• Management Fee Portion: A specific portion of the grant needs to be routed to a separate management fee account (e.g., Management Fee CR).

What we have done so far:

1. We have set up a distinct Billing Event associated with a specific Revenue Category for the "Management Fee" inside Project Accounting. This generates a separate invoice line item when the contract invoice is created. [
