background: sql 2000 with reporting services 2000.

from reading the MSDN, looks like one can install multiple instances of
reporting services 2000 on the same machine (for qa testing and
production and so on), but when I started the reporting services 2000
installation process, it didn't offer me the options of installing 2nd
instance. All i could see is either change or remove the existing
instance. can someone give me some advices?
thank you.

btw, I'm using standard edition of sql 2000 and reporting services
2000. for sql server side, i setup instances for testing, qa, and
production, I'd like to mirror reporting service site for that
sturcutre as well (testing, qa, and production). thank you
