Why would you want to limit AirMatch to a particular Group?
Suppose you have two groups in a site. If you were to enable AirMatch in one group and not the other, then AirMatch would not be able to perform the functions described in the docs, with trusted accuracy and reliability.
I would sugest this
article about AirMatch functionality. Perhaps it can convince you why it is best to use AirMatch accross the entire WLAN
