ArubaOS - guest per SSID

Hi Aruba guys,

is possible to make a guest per SSID? I've 4 SSIDs on AP but customer's network must be strict. I created a user in internal database of a controller but I can log on every SSID which is logic because I haven't seen an option to make it per SSID yet. I think it might be possible but it'd probably be a premium feature if I'm not mistaken.

Thanks in advance.
