How to reset a row count based on a column value?

Question

OracleBI Discoverer 10g (10.1.2.3)
Oracle Business Intelligence Discoverer Plus 10g (10.1.2.55.26)
I've got a Discoverer Plus report that shows item receipts, receipt dates, and if the receipt was inspected. I've got items that should be inspected every 5th receipt. There's got to be a handy-dandy function I can use to do this, right?
Item        Receipt Date      Inspected         
Bracket     1/1/2009               Y
Bracket     2/1/2009               N
Bracket     3/1/2009               N
Bracket     4/1/2009               Y <--let's assume someone didn't follow the instructions
Bracket     5/1/2009               N
Bracket     6/1/2009               N
Bracket     7/1/2009               N
Bracket     8/1/2009               N
Bracket     9/1/2009     I'm looking to count the receipts and reset the counter when Inspected = Y
Item        Receipt Date      Inspected     Inspect_Count       
Bracket     1/1/2009               Y                  0
Bracket     2/1/2009               N                  1
Bracket     3/1/2009               N                  2
Bracket     4/1/2009               Y                  0
Bracket     5/1/2009               N                  1
Bracket     6/1/2009               N                  2
Bracket     7/1/2009               N                  3
Bracket     8/1/2009               N                  4
Bracket     9/1/2009                                  5 <-- receiver should inspect on this receipt I'm open to other methods if mine seems like a dud.
