I have a slicer that is present in all 4 pages of my dashboard. I want to sync 2 by 2, so that slicer in the 1st page is in sync with the 2nd page, but not with 3rd and 4th. And then 3rd should be in sync with 4th.
But since it's the same field, it will only let me sync all of them at the same time
Based on my tests, it is unsupported to keep some slicers synchronized and the others synchronized. It will apply to all the specific pages. I'd like to suggest you vote on the similar idea and add your comments there to improve Power BI for making this feature coming sooner.
