Any way to inherit exposed filters on Block or Page displays?

Hi all -

Is there any way to use one exposed filter block to filter multiple views displays (including multiple page displays in the same View) at once?

I have a sheetnode view which is aggregating data from several other page displays, but the exposed filter only works on the data which is in the master page display.

In other words:

I have a View with 3 page displays. The Main page display is a spreadsheet view with 3 columns, A, B and C.

Column A has a calculated sum of Sales totals for the year.

Column B has sum of Sales totals for 1st quarter of same year.

Column C has cum of Sales totals for 2nd quarter of same year.

The second and third page displays are spreadsheet views with the sums for Column B and C respectively, which are then referenced by the spreadsheet in the main page display.

So the problem is that I can't get the exposed filter to affect all 3 columns, only column A. And I can't simply make the second and third pages attachment views instead, because in order for Sheetnode to work, those displays need feeds attached and as far as I can tell you can't attach feeds to attachment displays.

So how's that for a Tues night dilemma?

Any help is GREATLY appreciated.
