How can I create a pivot table with the PowerPivot Measure being used for the rows?

Building an inventory valuation model. Basically, taking data from sales, warehouse inventory, and stores to find lower of costs/sales value. I'm also applying a obsolescence formula that basically just says "if we sold 12.5% of our all available units over the year, then mark it as current, otherwise mark it as the last date we received it in the warehouse". This measure is named "Slow moving date".

I'd like to use "slow moving date" as a row in a pivot table, but Excel says that value can't be a row. How can I force it to allow the dates as a row without having to copy/paste numbers only from a different pivot to make it work?
