Make one slicer mirror filters of another slicer

I' have two slicers that each control two pivot tables. The slicers both are for the same field ("Department") but I guess the pivot table structure differences don't allow me to simply have one control all four tables.

Since both slicers contain the exact same options from the same field on the same origin table, I would like to problematically ensure that when department "A" is selected on slicer1, it is also selected on slicer2. When departments "A, B, & C" are selected on slicer1, the same are selected on slicer2. When filters are cleared... you get the picture.

Searched all afternoon yesterday with no luck. Anyone able to point me in the right direction? Thanks in advance!

Aaaaand, I'm an idiot. I must have originally created two slicers for the two sets of pivot tables, generating two separate pivot caches that could not be linked. As soon as I deleted both, and created a new one I was able to link it to all 4 tables. My apologies. Thanks for the attempted assist though

Ha! Some typos are more correct than the original text, eh?

False positive. It APPEARED to resolve my problem. I can have the slicer control either of the two pairs of pivot tables, but not both at the same time. Back to trouble.

Replacing the sensitive data in this document is a task in and of itself, so I may have to try tonight. Thanks and sorry for the confusion.
