Option to not focus the scratchpad when toggled on?

I know about dont_focus_before_close, which lets you toggle off an unfocused scratchpad. But is it possible to toggle on a scratchpad without focusing it? I'm using this for toggling live captions when I play video games, and unfocusing the game is not ideal (many games automatically pause when unfocused) and I'd like to avoid this if possible.

Is there a way to do this that I missed when reading the documentation, or if not, could this be implemented?
