How to make date picker show all months in Report Manager?

I am using SSRS 2008 and I have two date picker parameters.  In Report Viewer (BIDS), when I click on these parameters if I click on the month it lets me navigate to whichever month I want out of that year.  But when I deploy this report to the web (Report Manager), I have to click one by one to go back each month.  Is there a way to make Report Manager behavior mimic BIDS behavior?  How?
