C# Namespace/class alias in Visual Studio Html Source mode

Question

Is there any way to create a Namespace alias in a .aspx file (not code-behind .aspx.cs).

For example... in a code-behind file an alias can be created as follows:

using MyPanel = System.Web.UI.WebControls.Panel;

In html source mode (Visual Studio) a Namespace can be imported as follows:

<%@ Import Namespace="System.Web.UI.WebControls" %>

What I need to do is something like the following:

<%@ Import Namespace="MyPanel = System.Web.UI.WebControls.Panel" %>

EDIT/UPDATE: Obviously that does not work. Is it possible some other way without using code-behind? Yes, it actually does work if you remove the whitespace (hat tip @Alex below). Example:

<%@ Import Namespace="MyPanel=System.Web.UI.WebControls.Panel" %>
