Traffic Shaping by Host on Subnet

Question

I'm attempting to create a traffic shaping policy that restricts all devices on two of my VLANs to a maximum of 6Mbps per host. Trouble is, when I look at the setup guides for traffic shaping it seems that I'm limited to two options: 
 1. Apply a traffic shaping policy that limits the entire subnet to a certain bandwidth 
 or 
 2. Add all IP addresses on that subnet as individual hosts and then apply traffic shaping to each one. 
 
 I'd prefer to just create a policy that says "All hosts on subnet X are restricted to 6Mbps of bandwidth each", is something like that even an option? Or am I misunderstanding something somewhere?

Caleb, 
 you need to create a QoS where the policy association is per rules. 
 In this way, the QoS is applied to a firewall rule and all the users/IP in that rule will have 6 Mb as total bandwidth available (if the bandwidth usage type is shared). Otherwise select individual.
