Capture threshold date for donor

Question

For fundraising, I would like write a view to capture the date when a donor has reached a threshold of $10,000 within a fiscal year. There may be multiple gifts from this same donor within the year:
06/01/2008 $5,000
07/01/2008 $4,000
10/01/2008 $1,000
12/01/2008 $2,000
The pertinent date here is 10/1/2008 since that is the date when he arrived at the $10,000 level, all subsequent gifts do not matter. I want to be able to count how many donors 'arrived' at this level in a given month and not count them again for the remaining months of the year. It would have these fields:
ID CumulAmtinFiscalYear Date DateMonth FiscalYear
Any help is appreciated.
