I don’t understand how this template idea would be beneficial. I’m not trying to be difficult, I truly want to understand. Usually when I need to figure something out like this, I try to write out use cases as clearly as possible on a piece of paper and a pencil, because I get to erase and graph quickly and easily. Maybe spend some time doing that to see if you can figure out if it would be beneficial or not, and come back and share with us, because I at least want to know.
