Dynamic Group using new Hire Date field

Summary

Creating group for new hires based on the new hire date field

Content

I'd like to create a dynamic group that would use the new Hire Date user field where I could use > value

For instance:  I have a LP that I'd like to have the system auto-assign upon hire after a particular date.  Is there a way to create a dynamic group using the new hire date field to do this?  If so, can someone provide me some insight on how to accomplish that?  I assume you would have to use a > (greater than) qualifier, but I don't see where that is an option.
