I would think so. You would want to enter the month, and then, I don't know how DBlank did it, but you would want to filter out records where the MONTH() and YEAR() of the datefield that don't match. The rest of the report would be pretty much the same as what you already have, I suspect, you would probably add a group based on the date or DAY() of the datefield.
It's just a guess. I'm sure the DBlank can give a more complete answer, but that is my quess as to how you would proceed.
