Sure there is; Rand learned from Asmodean, and the others learned from him. Taim is self-taught to an extent, but learned from the Forsaken at some point too (either Ishamael or Aginor seems likely) before becoming one himself.
We've seen very few learn it with no training at all, too small a sample size to draw universal conclusions from. Nynaeve is the most prominent, and then there are... two other named wilders? Three?
Tauriel imo was an execution issue. Adding her could have been done well.
