Compensating Customer and SalesRep at the same time

Dear all,

I am aware that only salesrep is compensated for each transaction. Knowing that I can import supplier contact as resource (salesrep) and assign the compensation to it, however, it seems like I have too choose either one to be compensated. Is it possible for Customer and Salesrep (our sales employee, imported as Employee) to be compensated at the same time for one transaction.

i.e. 5% of Monthly Invoice Amount for the Salesrep and 3% of Monthly Invoice Amount for the Customer (Imported as supplier contact).

I have considered doubling the transaction amount and do a split of sales credit after putting the Salesrep and Customer in the same group, but it will be hard to maintain as the number of Customer is very large. Is there anyone who can share their experience in implementing this module with similar requirement? Any help is greatly appreciated.
