BPC 10 (EPM) Report Size On Static Report

I've created a static report because there are three different forms of GLs that need to be reported. What I did is create in Col B the GL numbers and then do active member recognition in Col C to pick up those numbers. However, after that I cant remove the numbers in Col B because it would take away the member recognized accounts in my Col C. As a result of this my report size gets really huge and slows down the reporting performance quality.
