I think you can easily do it in two ways:
- you can use AP gropu feature on WLC. This way you can use multiple VLANs on even same SSID name.
- you can use aaa override to override the vlan to which clients are connecting. This needs your SSID to be intergrated with radius server and configure the radius server to assign specific VLANs to specific users. This needs AAA override enabled on the WLAN. Tony posted the config example for this in his above post.
Those links will be useful to you:

- http://tiny.cc/czdkdw (this link is from config guide).
I hope the links explains to you all what you want to know
but note please that you are limited to up to 512 dynamic interfaces on WLC so if you have more than 512 VLANs this option may not fully work for you.
There are also limitation for number of APs per AP group depending on your hardware model. 5508 WLC for example can create up to 500 AP groups, not more. Having your run 7.2 I think you have new WLC hardware (5508, WiSM2..etc). which will usually support as much as 5508.
Hope this helps.
