How to restrict the "FCCS_Balance" Account values to the specific member of custom dimension?

Summary:

We have enabled Balance the Balance Sheet calculation for our client and it is calculating the different between Total Assets and Total Liabilities and Equity and posting it correctly to FCCS_Balance Account. However, the balance is posted at each level 0 member of custom dimensions. When we are trying to extract this data and send it to downstream consumption, It adds so many additional rows of data for each level 0 member where we have loaded data. Is there anyway we can post the FCCS_Balance values to specific members of custom dimension?
