Using rollup groups for Schedule 6 reporting

Hi,

 Our account values in the Chart of accounts is based on the current MIS reporting- however we would also like to use the same for Schedule 6 reporting. So what we have suggested is using rollup groups to group the Schedule 6 reporting entities together- this would help us report on multiple parents across hierarchies in the chart of accounts. My question is how do we use this to generate FSG reports for Schedule 6 purposes by leveraging on the roll up groups functionality which we are using.

Any thoughts on the above are welcome.

Thanks
