I wish there was a way to teach skills to Pets

Like having a pet transfer a skill to another Pet of the same family.

Some unique skills could be restricted from this.

This skill could be utilized in a third or fourth slot option for slots 1, 2, or 3 for you to pick.

The cost would be losing the tutor pet.

Could really expand options and let you greater customize pets or bring up your favorite pets with an expanded moveset.
