Tooltip for multiple value matrix

I have a matrix with 5 rows (Region -> Market -> Branch -> Rep -> Sales Order), and 2 values (Total Pipeline & Proposed In-Month).

I've created a tooltip that shows the breakdown of Total Pipeline by Sales-Stage.  This works fine for the Total Pipeline value, however, the In-month value returns the Total Pipeline values, due to the setup of the tooltip. I can reverse the tooltip value, but then the Total Pipeline value would show the In-Month value.

Is there a way to setup my tooltip's graph to show a different value, depending on which value I'm hovering over?

Thanks in advance!
