corgan ticket limit

So, this 2 ticket limit…

I bought two during the pre-sale, but I need 4, to be honest. If I attempt to buy 2 more during the public sale on Saturday, will it cause my original order to be cancelled? If so, is there a way around this (other then obviously buying at the club itself)? If I bought 2 more through the phone instead of the internet portal, would that work?

I obviously understand if you can't/won't answer questions about how to get around your ticketing agent's restrictions. Figure it wouldn't hurt to ask, though.
In the future, you should probably direct these kinds of questions to the Tickets.com folks.
