Same here, though I forgot to check custom battle, but that's what confused me too.Yeah you can definately do it anytime.
Okay well having looked in the custom battle section I can confirm that my Special Reinforcements and my Amazon units are available after activating their codes. They just don't show on any "DLC" tab like the FAQ says they should. Odd but hey, they're there.
