Cab sim only for one output (L/R)

Hey guys,

So far I've been pretty impressed with the Kemper (Profiler Rack). But there's one thing I'd really like to do:
On one output, for example the left one, there is cabinet simulation (FOH) and the right one runs into a external power amp and from there into a real guitarcab.
I don't need to use parallel paths...otherwise my rig on the two outputs can be completly identical. The monitor output is meant to be used for monitoring.

I would really appreciate if you could help me with this issue.

Best regards,
JayPuddy

I know about this solution, but the monitor output is already in use.

I'm planning to run the monitor output to the monitor system...
