Is it possible to override default content in Korbyt? If so, how?

Yes.

Create a playlist with the name “Korbyt Default Content” and with the tag “korbytdefaultcontent“.

All other playlist steps proceeded as normal.

You do not assign this playlist to any players, because it is simply replacing the default playlist of Korbyt Images. This playlist will now play “by default” when no other content is present or assigned.
