Method for Randomly selecting sources within a group inside a scene?

[ToTheLifeboats]

Apologies if there's a plugin for this. Before my livestreams I play a music video while people filter in. I also have quotes on another part of the screen. I'd love for one source in the group to be randomly toggled to visible while all other sources in the group are not visible when the scene is selected.

i.e. Plays a random media source or displays a random text object (quotes)

Is there a way to do this?
