Passing Custome Create Date Using Membership CreateDate() Method

Hi,
I want to pass create date in Membership CreateUser(..., ..., ...) method. As It's only providing no such method of passing custom create date of an user(s). Is there a way to pass it? I'm using .NET Framework 2.0. If there is no such way then have any idea my Microsoft is not providing this functionality for passing custom value(s) as store procedure is implemented all the table parameter(s).
