Hi
That last bit has been on my mind lately as well. I have a few roasters, but typically roast with only one. I'm thinking of a roast template feature. But even without that, if only one roaster is defined, I agree - it should default to that.
About the copy roast. You can long tap on roast in a list to copy it. That will take care of the roaster, profile (program) and the roasted items. Did you know about that feature? Or are you asking about some way to automatically target that particular roast and do it all in one fell swoop?
