Using a dropdown to select the Dimension of a column in a report

Hi Experts

I am building a report on BPC 10.1

What I would like do is set my column/row dimensions using a drop down chosen by a user. So for example, A user will select from a drop down the column dimension and from another drop the row dimension, thereafter refreshes the sheet and the data will populate.

I know using EPMDimensionOveride you can override the member or members from the column/row, what I want is to change the whole dimension not just its members within.

This was a extremely simple task in BPC 7.x where you would just say Column axis equals to dimension in dropdown.

Thanks

Regards
