Feature Request: Option to simultaneously record own stream to file.

I would like to have the option to save the streamed video to a file.
While I could do this simultaneously with OBS or GeForce Exp. this would also
mean to encode the video twice. And streaming the OBS output with Discord adds
a rather significant delay, which would also be bad since some scenarios are kinda
time critical (21st man wow). Also it's rather cumbersome to configure while it could
be just a checkbox and a filepath in Discord.
