[Feature request] Show only on one output

When I bring up sov, it shows on both my outputs (DP-1 and HDMI-A-1). I only have one workspace on HDMI-A-1 so the overlay is only in the way there (especially since someone else might be watching video playing on it). It would be nice to be able to tell sov to only show up on one output, but I haven't been able to find a way.
