custom c# item teplates

Question

I wanted to make a template which would be affected by DateTime.Now or something similar.

For example, on 2015-08-07 at 12:45, if I click "add Foo class" to project, then this should land in the new file:

    class Foo201508071245 : Foo
    {
         public string Boo201508071245 { get; set }
    }

Is this achievable?
