A few things to clarify from the start: Hero hands are always automatically excluded from Range Research.
In regards to that, if you have mixed up your own hands and your friends' hands played as Hero, it's recommended to use 2 separate databases for accuracy of your own results in RR.
Now if you want your friends' hands also excluded from field study in RR, you can just import all of your hands at once and if your friend there is considered a Hero, his hands won't be included in the report.
To analyze your own stats you don't need RR at all. Simply add all of your Hero nicknames to one alias in Configuration -> Aliases and then open this alias popup in the main window. The same applies to Reports\Sessions, simply select your alias there.
