Schedule a report with the system date imbeded in the file name

Hello,

Could anyone tell me how I can schedule a crystal report with the system date imbedded in the file name (FileNameYYYYMMDD) through BOE? When I scheduled the report through BOE, I gave a file name and selected Attach Date Time, but the file name is coming out slightly differently and with the time imbedded as well (FileNameYYYY-MM-DD-HH-MN I think). Is there a way to change the default system date time format in BOE so that the date stamp comes out the way we want it?

Thanks!
