Cisco WAN :: Exempting NAT On ASA 5505 Version 9.1(1)

I have been using ASDM on a "Cisco Adaptive Security Appliance Software Version 8.2(5)" for a long time and in order to route packets among the interfaces without NATting the packets, I have always been using the function "Add NAT Exempt Rule" under "Configuration -> Firewall -> NAT Rules". Everything has always been working fine.
 
Now I am trying to use ASDM on a "Cisco Adaptive Security Appliance Software Version 9.1(1)" and I cannot find how to do the same operation: the "Add NAT Exempt Rule" option is no longer available and the only way to make the traffic passing through seems to be NATting it on the OUTSIDE interface.
 
where I am mistaking? My goal is to let the traffic passing through from the inside interface to the outside interface without being translated.
