Introducting a "main switch" for slicers

I come across an unachievable issue that I have raised in the forum: that is to make a "main switch" for slicers. Whenever the value of the main switch is changed, all the slicers with the same value across different tabs will also change, whereas changing the independent values of all other slicers will not affect the main switch.

This is a quality-of-life improvement for both developers and users, if it is decided that all the slicers are not sync-ed in order for flexibility.

It will be grateful if this can be included as a new function. I think either a new type of vis particularly for this purpose, or the options for "unilateral sync slicers" will do.
