It doesn't matter where you put the move really, as long as it is under your Attack list. if you look at some veteran's profiles, they have their moves organized alphabetically, or by physical/special/non damaging. As long as you list your attacks all in one stream, you can order them however you like! I personally like to keep mine separated by lvl up/egg/tutor/TM/etc, so if you are going to do that, just make a new sub category of moves for events/NYPC!
If you have anymore questions, feel free to shoot me a VM :)
