For example, we make our own bread, but like to switch up the ingredients from time to time. Re-entering the full recipe is a PITA, so it would be great if I could select the "seed" recipe and copy it into a new one, then rename and tweak the ingredients in the new one, leaving the original alone.

For reference, we primarily use the web interface, not the iOS interface.
