Apply all slicers & Clear all slicers buttons - without bookmark

Do you want to make multiple selections across all the slicers on your report page and then apply them at once? or Do you want less interaction with visuals for each slicer change?

let's say we have multiple slicers on your report page & For each slicer, you have to select some values, now you want to clear all slicer's selected values in one click. Traditionally, We used to create a bookmark and button to clear all filters on the slicer.  

Power BI released a new button under optimization called - the "Apply all slicer button".  This button can be added and formatted just like another button in Power BI, and also can be added directly from the Optimize ribbon. 

Apply all slicers and Clear all slicers buttons impact all the slicers on the report page. You cannot pick and choose which slicers you want each button to control. They also do not control the filter pane.
