Remove namespace or classname from VB.Net when used in VBA [duplicate]

I'm writing a COM DLL for use in VBA using VB.Net. Here it is, in all its glory:

Public Class CompPl32
    <Runtime.InteropServices.ComVisibleAttribute(True)>
    Public Function MyUncompress(SrcSt As String) As Integer
        Return 0
    End Function
End Class

When I look for this in Excel's VBA editor, I find the dll/tlb with the projectname/rootnamespace "CompPL'. When I refer to it in code though, it's...

Dim pl As CompPl.CompPl32

Which is kind of ugly when you're trying to match the API of non.Net COMs. Is there a way to remove one level of the naming so it's either just CompPl or CompPl32? I tried putting it in a Module but you can't import just the project namespace, it has to have a class name in VBA, and changing the root namespace to nothing results in a blank string that is confusing.
