Limit "Group DPSK" to a number

Question

Is it possible to limit the amount of users that are allowed on a "Group DPSK"?

Ps, DPSK needs to have the expiration date on the unique key itself, and not the WLAN (What a poor design)

I am wondering why no one from Ruckus has responded to this Question.  This is really a poor design if you cannot control number of users on Group DPSK.
