Rotating data in a QR report

I have a question I hope you will help with.  I need to create a approach
for a report using various datafields in a rotating fashion. Based on fiscal
periods, fields would rotate like f13 f12 f11 ... when period 13 reporting
is needed f1 f13 f12 ... when period 1 reporting is needed.
I am still using QR standard ver 3.

Another question about QR.  Is the prof version worth the money?
