skill task groups

[Yushi]

Ok, first I want to make it clear that I'm not asking how to level. I'm asking about sets of tasks that are typically available for all skills.

I was playing an alt earlier today that had never done any fashioning at all. I decided to be super lazy and just set him to complete all the "basics of" tasks. I then planned to set him up for the "advanced training in" tasks (I believe that's what they are called). However, I couldn't find them anywhere.

Do they not exist?

If they do exist, does anyone know where I can find them?
