How to enhance the COPA0005

Dear COPA experts,

We would like to use COPA for reporting. When doing valuation of Billing in COPA using a standard cost estimate this is done for the whole Controlling Area as COPA doesn’t limit on any other organizational level. However we would like only Company Code 0073 and 0069 to be valuated in COPA . I donot know how to do. Can I enhance COPA0005 to do it?

Thanks a lot.
