Is it possible to pull cycle time by campaign? We're able to pull cycle time on our projects, but wondering if it's possible to do it by the larger campaign (group of projects). Thanks!

I am trying to run a report that shows quarter over quarter, how we are improving (or not) on forecasting hours on our projects (planned vs. actual). I tried to create a calculated column for the % difference in final billed hours vs. what we estimated, but I'm having trouble getting that to display...
