NPS Network Policy based on SSID??

Hi..

I currently have multiple SSID's in my network. I'd like to create an NPS network policy that the condition is met based upon the SSID that the user is on.. 

Example: If a user is on SSID1 they would get this policy. If a user was on SSID2 they would get this policy. 

Or, do I have to create a separate NPS server for each SSID that I want a different condition for??

If it helps, I'm running Windows 2008 R2 Domain Member Server with NPS.  

Thanks... Frank
