"Learn everything" function

Good day. There should be function like this. In vanilla version, when bot is going to a class trainer he opens skill panel, filters it to show only Available skills and then just learn everything. How do i call this process myself? Is it possible?

Trying to make it learn professions and skills with when i need to instead of when bot decides to. I can run to NPC, i can open a gossip option, but i do stuck after this.
Learn skill by name would be even better, but i doubt there is a thing like that.

Any advices much appriciated.
