I have the profile editor, but unless I've missed something it seems to offer only two methods of making profiles:
1. Manual tweaking, which seems rather slow, tedious, and error-prone.
2. Matching the standard colors from a colorchecker.
I'm looking for something a bit like option 2, but where the user has the option to say what the reference colors are, or even better to just give a reference JPEG of the chart.
