Link more than 2 Pivot Charts Dropdown lists

Hi Everyone,
I'm new here and kinda playing with excel for my report.
I have a 5 pivot Charts and i need to keep all the drop down list link to the the first list.

If the January is selected on the first list then all the other 4 should be January.
I'm kinda losing my mind a little bit as i have no idea how to do it.

I would really appreciate it if someone could guide me how.
Hoping for a positive feed back from any one.

Thanks and regards.

Reign
