PNA-X smc channel power settings scpi help

I'm using the latest A.09.90.05 firmware. In looking through the help file under the 'Programming' section, under the 'SENSe:MIXer:' tree, they have commands to set the RF input power (i.e. 'INPut:POWer), and the LO power (i.e. 'LO:POWer'), but I couldn't find an entry to decouple the port powers or to set the IF output power. (i.e. a command like 'OUT:POWer')

For example, I want to setup a SMC channel using Ports 1&2 of the PNA-X to hook up to a downconverter RF and IF ports. (using embedded LO). I want to set the Port 1 power (RF side) to be  -20dBm and Port 2 power (IF side) to be -10dBm. 

A followup question is that if there is a SCPI command to set the Port 2 power for an SMC channel, will that automatically set the appropriate Port 2 source attenuator setting, or do I have to set it manually via 'SENSE:POW2:ATT ' command? For instance, if I want Port 2 power to be -40dBm, then the Port 2 source attenuator should be set to at least 10dB.
