I ran into this myself just as you illustrate - in doing target temperature variations on Sous Vide recipes…
While copying would help a lot, I also suggested another means in a recent post of mine, though fear my wording wasn’t very clear, or at least to those unfamiliar w/programming terms or concepts. But in general the idea is to allow for a recipe to refer to not a fixed/specified numeric temp or time, but rather to a “named variable” instead that can later be specified each time one runs the recipe, a means to have a single master recipe that runs with varying temps or times each time it’s run…
Even better would be to allow for several recipes to refer to the same master recipe, with each recipe specifying values for each of these “named variable” temps or times referenced in the master recipe…
