You can just have a forwarder for each: 

 
 virtual INSIDE_VLAN71a { 
   ip forward 
   destination 172.16.72.0:any 
   mask 255.255.254.0 
   vlans Vlan_80 enable 
 } 
 virtual INSIDE_VLAN71b { 
   ip forward 
   destination 172.16.74.0:any 
   mask 255.255.255.0 
   vlans Vlan_80 enable 
 }

If there is no route locally defined for 172.16.75.0/24 that should go elsewhere, you could also just summarize 172.16.72.0/22 as a single virtual, though this is less accurate and could cause problems for you down the road. It's an option though. Adding the virtual simply "allows" the traffic through, the routing for said destinations needs to be present for packets to flow.
