The base is there to mod this script as you need it. TM put the piece together, just use the one you need to perfrom the task you need.
I have multiple tamer and I never use TM vet trainer. I utilize Panthers_petVet_Trainer, a mod version of it, until I find something better.
You need something to accomplish something in game. so this is the perfect project for you. Build a Vet script for hunting. Do you want to hep with magery or aids, maybe both.
