how to book each invoice line to separate revenue account

Summary:

Multiple invoice lines from Projects are getting booked to one revenue account. We need to book them to different revenue accounts.

Content (please ensure you mask any confidential information):

AR invoice imported from Projects is created with two lines (based on the event types). However, both the lines are getting booked to one revenue account.

We need to book them to different accounts. I have tried using Transaction Line Description also as one of the sources on the account rule but SLA is not splitting based on the line description.

Any help is highly appreciated.
