Disable collection on all layers except one?

Question

I have 10 layers and every time I make a new collection I have to click on each layer to exclude collection from every layer. For example, I created collection on layer 1 and need it to be enabled only on layer 1. Is there an option or hotkey to exclude collection from all layers except this one?

You can just click and drag down/up and it will select/deselect multiple at a time. — scottywood, Feb 07 '20 at 20:50

The following Add-on code can do this for you. Save the code as oco.py and install that file as an Add-on in Blender. You can then activate it when searching for Collection Ops in the Add-ons section of Blender.

Once done, right-click in the Outliner on the collection you would like to exclude for all other View Layers and select the command on the bottom:

Here's the Add-on code:
