Is there a way to have Excel's CUBESET function take multiple Sort By arguments?

I'm trying to have a CUBESET function that returns ranked products by sales for a particular timeframe. I can get the sortby argument to accept [Measures].[Product Sales] and a single date utilizing Concatenate, however it would be preferable to have [Measures].[Product Sales] and a date range. I currently have the date range in a different cell as another CUBESET. Anyone know how I can do this?

Assistance would be greatly appreciated.
