What Does "Multiple" Mean in the Outs of a Channel?

[Favedave]

I assign outputs to channels, and normally, it just shows Main or Drum Buss or whatever I've assigned it to.

But a few times now, a channel will show "Multiple" as its output. I have no idea what this is. When I click on it, the Focus window only shows one output selected.

Oh, I just figured it out. The channel in question is feeding a sidechain to a Trackspacer plugin on another channel.

From the Luna Manual:

ASSIGNING A TRACK OUTPUT TO MULTIPLE DESTINATIONS --

You can assign the output of a track to multiple destinations. To assign an output to multiple destinations, click the output assignment slot, then in the Output browser, Shift-click or Command-click the outputs to assign. The output is then labeled with “Multiple.”
