How to use Project specific attributes for the Accounting derivation of AR Invoice

Summary:

I want to use Project-specific attributes like Project Billing events, Project organization to derive certain segments (Natural account and CC respectively) on the AR invoice receivable account.

I tried creating a mapping set of Billing events and NA and used it on the Account rule. But I am not able to add that Account rule to the Invoice Default Receivable Dr. Side of the Subledger Journal entry rule set for Invoice Event Class.

Could you please suggest some way to achieve this requirement maybe by using Auto Accounting or SLA of receivables module?
