Hello,
I was wondering if there was a way to compare 2 similar upgrades in the same run. Say you want to compare the results of changing attic insulation to R-38 vs changing attic insulation to R-49. Is there a way to just do 2 apply upgrades in one run (one for R-38 and one for R-49)? Or do you have to do 2 separate runs to see the affect of each?
