Response SLO condition for service

Hi

need to create response SLO condition  as combination of  product type and severity

service area : incident

example : 

product type 1 " severity 1  --  duration 1:00:00 

product type 1 " severity 2  -- duration 2:00:00 

product type 2 " severity 1  --  duration 1:00:00 

condition based onlu in severity is working fine, but need to combinate severity with incident product type.

Regards
