How do you reset the training counter with the console?

Question

I can't find how to reset the trained this level-counter. Is there a command to do so via the console, and if so—what is it?

Answer 1

There doesn't seem to be one. However, since you're using the console anyway, you could reproduce training with advskill to level up the skill and then remove the proper amount of gold from your character with removeitem.

player.advskill <skill> <nn>
player.removeitem f <price>

This article has the formula for how much gold it costs per level and this article explains advskill in detail.
