Multiple 1 month Zune Pass registered at once?

[lip]

Hi,
I got a bunch of 1 month Zune pass cards for Christmas(they were bought at bestbuy)...can I register them all at once to add up to say 3 months or do I wait until each one is about to expire?

I could not find the answer to this anywhere.
Thanks.

I can answer my own question...you can enter them all individually and it will advance the pass subscription by the amount of months you have bought...
Since I'm in Canada I was hesitent to try this but I had no alternative anyway so I went ahead and it works fine...
