Getting Difference Between Two Measures That Are % of Grant Total

[Anonymous]

Hi Everyone,

I could really use some help with this. I have the Matrix below 

All the rows are Measures that I have created. The Prior FY % and Current FY % rows are just the same measures as Prior FY # and Current FY # but 'show as % of grand total'. 

I am trying to create another Measure row called Ratio Change % that would be  Current FY % - Prior FY %.

Is there a way to calculate this without having to create percetnage measures separate from the ones I already have?? Any help and guidance and in the right direction would be much appreciated!

@Anonymous , looking at this seem like you have to create a new measure, or you can consider calculation group
