change filter options when using drill down

Here is part of a visual showing account 130, average parked at noon, this day of the week, parked at noon today, and comparison percentage today/average.Notice cars parked are 178 and 207; comparison percentage is 116%. Drilling down to parking areas within the account shows the following:

Now, my client only wants to view, at the account level, only those accounts that are either below 80% or over 120% of average. When I apply that filter at the account level I get the following:

I want account 130 not to show now as the comparison percent was 116%, but it does appear with different totals for cars parked and a comparison percentage of 122%. This is because the "less than 80% and greater than 120%" filter got applied to the area level as well as the account level, so some of the areas don't appear now because of the comparison %, the totals drop to numbers that don't represent the entire account. 

In other words, I want the filter to apply at the account level, but when I drill down to the account area level, I want all areas to appear regardless of the comparison percentage. How can I make this happen?
