I am not sure what you are asking to be changed. Are you asking that when an animal needs training they will automatically move to the trainer, instead of the trainer moving to the animal?
In real life, it would never work this way. If an animal loses training, they would not come back to be trained. Someone would need to go find the animal and train them.
When I start a new colony, I restrict my animals to a very small area until they are trained. As my colony expands, I use colonists with the Fast Walker/Jogger traits and give them Bionic/Archotech Legs and a Fast Mover Persona weapon so they do not have a problem traveling on the map.
When non-hauling animals are moving, they only move at about 1/2 normal speed, so there is not a problem with your trainer catching up to the animal.
I restrict my hauling dogs to the inside of my base only and a small portion outside. Then I train my other animals in hauling as well, and restrict them outside the base except for the same small portion. When a raid happens, my outside animals will haul everything to the stockpile that the dogs have access to, and the dogs will bring everything inside.
This means that my animal trainers never have a problem catching up to the animals that need training. My dogs are always nearby, and my other animals are walking very slowly when they are not hauling.
The best practice is to train your animals in all categories as high as possible. Skill decay does not affect all skills at the same time, unlike colonists. They only lose training in one random skill at a time.
If you train them in all skills, you pay a heavy training cost initially, but the benefit is that it it takes a very long time for them to forget how to haul. It also means that when you send a caravan out for weeks at a time, your cargo animals will not leave your caravan because you are not training them.
