Hi all! 

For context, I am currently running a program that has quarterly surveys. I am on Q2 of this survey, and of course the goal is to see trends from Q1. The hierarchy mapping for Q2 is pretty straight forward, but my question is, what does it look like when I have three projects / hierarchies?

Right now, I’m mapping between Project 1 and Project 2 (both ways). For Project 3, will I have to map both ways to Project 1 and Project 2? Or just Project 2? The math is mathing on the level of work this will be if I have to map both ways for all historical projects .
