As much as I like the new Drillthrough actions, it seems a bit lacking in that it does not also pass through any report filters that are active on the source report on the source report.
This is definitely helpful for instances where you could filter a range of dates, and where it would be impractical to add date column to the drillthrough table (since it would change the grain). Taking report/page filter (such as slicer) would allow not having to add the filter to the column.
