So I have 3 PS3's, one for each TV (a decision I now regret, but that's another story). So apparently when they reduced the number of consoles tied to an account from 3 to 2, the newest PS3 automatically fell off, so I can't activate anything I purchase on that PS3. I'd rather not remove all my purchases from any ps3, but I want to know:

is it possible to purchase to designate which ps3's are allowed to use which purchased content?

for example, can i use download 1 on ps3s 1 and 2, and download 2 on ps3s 1 and 3, and download 3 on ps3s 2 and 3?
