query reduction to be applied at report level

[WWang2]

When there are multiple slicers\filters used on one report, it's not really helpful to turn on this feature. It would be nice to select all the filter values and apply them at once.

I have a direct query with five slicers. With query reduction enabled, there are five apply buttons. Each time a slicer is updated and Apply is clicked, Power BI re-runs the query.
