How to deauthorize all computers more than once a year??

Hi,

I have set up my new computers and tried signing in to itunes.

Due to all 5 computers are already mapped to my apple id, I am not able to authrized my new computer.

I don't use the 5 authorized computer anymore, so tried deauthorize them all.

However, I can only deauthorize them all only once a year.

I may use that chance already, so I must wait until that year be passed.

Is there anyway I can remove currently authorized computers, even though the year has not passed yet?
