sometimes i need to open project in DX12 mode (just temporarily, so i don't want to setup commandline args).

Would be nice to open project, while holding some key down (like shift or others)
then it would use those arguments on project launch.

TODO

• add setting field for "quick/temporary launch argument" (then can setup any argument there)
• then while holding some key down on project launch, apply that argument during process start
• later, could have few more fields or some kind of list (shift = -forcedx12, alt = ...., ctrl = ...)
• OR, holding a key would open startup dialog, where you can pick your own settings or set temporary commandline arg
