Please provide a command line option to change the order of connected PC's for Flow control. A screen with Picture By Picture (PBP) such as many of the Dell monitors support switching inputs to show left/right in PBP mode. Not only for convenience, but often to determine which input gets access to audio out.
If inputs are switched, then it's no longer aligned with the Flow setup. Switching L/R for PBP is something that happens all the time and it would be really useful for power users to have access to a command line interface to change the order of the computers.
