Webcore - Can we add an option to pause an entire category?

I have several webcore categories. My Christmas category has 12 pistons. Can we have an option to pause all of the pistons in a particular category?

Interesting thought.
I just change a switch device to True or False.

I have a virtual switch embedded in the pistons top condition; If blnXmas is True then do else end.

Or, I have a piston that pauses and resumes a group of pistons on a device change like the first example.
