GETPIVOTDATA To Include Hidden Items/Fields

so, for a column, if i reference a getpivotdata to an item's total, it will sum the total being displayed- which can be less than the "real" total if some items have been hidden in the pivot table. what i want is to have getpivotdata (or another function, i don't care what it's called) to always sum an item's total for the entire pivot table range- irrespective of whether certain of it's details have been hidden. ideally, what i'm trying to do is:

sum the total of an item for the pivot table range
sum the total of the column from the original data
compare if they are not equal, the pivot table has not been refreshed

i need to do this without macros. (it's my "solution" to see if macros are enabled or disabled- because my pivot table automatically refreshes data based on macro)
