Custom Channels for Adsense for Domains

i just linked all of my parked domains on adsense for domains with their respective channels to monitor which domain is making me more money than the other. it was easy to link but was wondering why google adsense wouldnt make channels automatically for parked domains? i know they do for blogspot blogs but why not for this too?
