For a few different reasons, the copy feature constructs the new roast's
Data Curves from the profile of the source roast. So, if the profile in questions contains
Curve Templates, those will form new data curves in the copied roast.
If you already use profiles containing
Target Curves as a means of targeting temperature data, just add the corresponding
Curve Templates to you profiles. Then, when you copy a roast, the data curves will automatically be configured. If not, you could create 1 general profile with Curve Templates and use that for all roasts.
But, a better solution for the scenario you mention is to use the
Build Roasts by Yield feature. In the roast list, tap the gear icon in the bottom toolbar to access it. Then, just enter your desired roasted yield weight, and choose the appropriate profile. Roastmaster will build all 17 roasts at once. The same rules apply for
Data Curves using this feature - the
Curve Templates of the profile you choose for building the roasts will be used to create those data curves. If those curve templates have their probe binding set, the curves will be linked without any additional input on your part.
This screencast talks about the process so you can see it visually...
