VS 2010 Code Snippets - C# equivalent of <Imports>?

Is it possible for a C# code snippet to add lines to the "us开发者_StackOverflow社区ing" block at the top of a .cs file? I see the element for VB but that doesn't work in C#.

From MSDN:

The Imports element is only supported for Visual Basic projects.

There is no equivalent for C#
