The current Prism2/2.5/3 firmware does not support this.

Well, you could try to switch between the different SSIDs, but it would
be quite horrible hack and I would not really recommend trying to get
this working with the current Prism2/2.5/3 firmware. Selecting a
different wlan card design would make this much easier. The card would
either need to provide Probe Request frames to the driver or support
multiple SSIDs internally in firmware.
