A way to only sync album picks with iOS?

I have a smart album that filters by 4 stars or above and I like to keep these photos synced at all times with my iphone/ipads. It works ok except that when we do multiple edits of the same photo in a stack they all get sync'ed. So if we have 7 different style of the same photo, all 7 would go into the devices. Album pick seems to have no effect with this. Is there any around this? I don't see any customization on the iTunes side so perhaps there is a way to make a smart album that only includes one photo of each stack?
