Can inactive sound devices be displayed by default?

plasma6 kcm_pulseaudio’s (apparently new, unless I previously missed it) ability to display inactive devices:



…is really useful to me, because without that feature, I scratch my head, wondering where certain devices are, until I remember to enable it again. I visit that KCM a surprising amount.

Basically, I have yet to have a reason to disable it, so I’d like to be able to keep it enabled by default. However, I see no way to do this. Perhaps there’s a configuration file I can change (I hope)?
