Possible to add "Invert Primary/Secondary" display option?

[kayakyakr]

I've got a uniqueish situation: trying to use an HDMI dummy, but anything plugged into the HDMI port comes up as monitor 1 while the 2 DVI ports and the display port each give me monitor 2.

I appreciate the DisplaySwitch.exe hack, but just need an option to switch to primary screen while streaming and secondary while not.

Was going to try out https://sourceforge.net/projects/monitorswitcher/ combined with your on connect/disconnect actions (I'm still using gamestream here), but would love it to be native. Thoughts?

Spent some time with the dummy and created: #19

Note: this didn't fully solve my issue because I ran into issues with fullscreen sizing.
