Disable auto sign-in on the PSN

[Number45]

Anyone know how to do this on the store? I want to use my main profile all the time, so I don't have to mess about copying saves and stuff, but I'd like to determine which store I go to by the account I use when I start it up. But since I checked the auto box when I first created the accounts, it doesn't ask and I can't find a setting for it.

Thanks

Found it. For anyone that's interested, hit Triangle when you have your name highlighted in the Friends list.
