Need to compare 2 columns in an OTBI pivot table

Summary:

I'm wanting to find out if this requirement is possible within OTBI. I have 2 dollar amounts 1 for each date paid. I need to compare the 2 amounts and look for changes from 1 period to the next. We can achieve this in excel but it would be a time saver if it's possible directly within the OTBI analysis. If there is a better way to achieve this result I'm open to suggestions. Thanks!
