How to change black settings of an ICC profile in i1Profiler?

I've done this before but it's been a while, I'd like to take the new Gracol Uncoated profile and change the GCR setting to max and resave.

If in the profiling window, on patch set, if I double click the GRACoL2013UNC_CRPC3.icc profile, it loads, go to measurement window, double click on that same profile again, edit profile settings to max black and then generate a new profile with a new name, is that the way to accomplish this?

Seems that's how I did it before.

Thanks
