Action groups for fuel tanks and batteries

[More Boosters]

You know what would be amazing? The option to set everything to an option group where we can toggle whether their content will be blocked or not. Going through 20+ batteries disabling them all by hand is rather inconvenient, it would be great if we could do it by just setting up an action group and then pressing the button as we need it.

That's a good idea, I can see it being useful for long hauls.

Are there anything else that can't be set to action groups? I thought pretty much everything that can be toggled could be set to action groups.
