Insteon Integration created a dashboard panel called switch with all of my scenes

I’m new to HA & the Insteon Integration. I’m using a configured PLM I moved to HA. So far, so good.

I just named all of my scenes, and discovered that they are all in a panel called “Switch” in my default dashboard. The panel has a single switch near the title that is off by default. In its off mode, none of the underlying scene switches will function.

What’s my question? I don’t understand the overall function of the top title switch. If it causes the Insteon Integration to try to turn all of my 14 scenes on at the same time, it will be a broadcast storm, ALL ON disaster.

Anyone have experience with this, how it’s to be used?
