Transact SQL :: Only Store Datetime Values Down To Nearest Minute Automatically Without Using Trigger

Is there a way that I can do this at the table level to automatically handle the rounding of seconds, etc. down to the minute automatically without having to use a trigger?  

Here is a very basic example of what I am trying to do:

--example:  '09-22-2007 15:07:18.850' this is the value inserted into the table by the code
select getdate() 

 --example: '2007-09-22 15:07:00.000'  this is the value I want to store in the table
select dateadd(mi, datediff(mi, 0, getdate()), 0)
