Is it possible to use multiple wifi dongles in Linux with one of them setup as a hotspot?

I was wondering if it were possible to have 2 or more **WiFi USB** dongles setup in Linux with each having a different **SSID** and different networks with one setup as the gateway to a **WiFi router**? I.e. [tag:Linux] with 3 **WiFi** dongles; wlan0, wlan1, and wlan2. * wlan0 -> WiFi router * wlan1 -> SSID="abc" * wlan2 -> SSID="def" where "**abc**" has a default route through wlan0 and "**def**" only has access to the w.x.y.z network I've tried googling but with little success.
