Disable all Extensions in project button

Seeing how unstable cubase & extensions are, it would be really nice to have a disable all in project or even a menu where you can see all the extensions.

I recently had a project with 400+ channels.
Every time i tried to change the bpm, cubase would immediately crash.
It was trying to recalculate things with Spectralayers.

So of course i know i had to disable Spectralayers, but finding all the channels with it enabled was quite a task.

If there was an easy way to disable all, or some kind of dropdown to deselect.
Really, any kind of way to circumvent this situation could be helpful.
