RUNNINg total for distinct count measure across the time dimension

Hello,

I want to create running totals within my cube for one of the distinct count measure that I have

And following table shows my measures and required running total measure values.

“Unique Users” measure is distinct count measure of users.

And “RunningUU” measure is just sums the numbers, but it should be distinct count of users.

My goal is to create running values similar to “Actual Running Total should be” measure in the following list.

And these running totals should display for all members in my time dimension.

Please let me know if anyone knows creating running totals for distinct count measures with time dimension.
