MemberName function in FR

Hi All,

I am in the process of creating a new FR report for a cash flow statement. In one of the cell, I am trying to use the MemberName function to get the name of a dimension from another column.

It works when there is only a single column, but I am trying to figure out if the function works if it has to reference a range of columns?

Example:

<<MemberName("Grid2",A: P, "EmployeeShareholder")>>  

My goal is to name all the dimension members that will have a value in the range [A:P]

Any inputs or alternative methods are greatly appreciated.
