week start date

Is there any way to change the week start date for crystal reports to Friday? Our payroll goes Fri-Thurs, but I can't figure out how to make crystal reports start on Friday instead of Sunday. I can do it in Active Reports, but I like Crystals Time Card Report better. On that note, does anyone have a better time card active report than the default? I got the one off Jean Hollands site, but it's not much better. It would be nice to have one that totaled all the hours for each date. Thanks for any help. Craig
