Can I use one thread toward multiple trades?

Let's say you have a thread that could feasibly be used toward Warrior, Warden, Gamekeeper and/or Caretaker (your wolf was busy that day!?).

I loled at this for some reason. So, first she caught some breakfast for the pups, then she brought them with her to the borders for a patrol, then she showed them some fighting moves, and then tucked them in at night after their busy day? >_> Lol. It's good to know though that one thread per trade.
