Add Simple Language Support to Visual Studio 2010

I'm developing some VBScript using Visual Studio 2010. The native support for this language isn't great, so going forwards I'm hoping to look into taking advantage of language services / VS Extensions to allow me to improve support for these languages. For the moment however I just want to make my life simpler by adding a couple of features:

• Allow the VS Task List to recognise my 'todo: comments
• Allow c# like #region...#endregion functionality to make it easy to break the script up into more easily readable blocks (to comply with VBScript I'd stick an apostrophe before the hash to make it a comment).

Is there a simple way to do this through configuration in VS, or do I have to create an entire language service to get this functionality? What I'm asking may be impossible; but thought it worth asking on the off chance.

Thanks in advance.

My bet is you could do the tasklist stuff with a simple extension: http://msdn.microsoft.com/en-us/library/163ba701%28v=vs.80%29.aspx

But to do the #region behavior I'm fairly certain you need a simple stripped out Language Service to get to the Source's AuthoringSink http://msdn.microsoft.com/en-us/library/microsoft.visualstudio.package.authoringsink.addhiddenregion.aspx and http://msdn.microsoft.com/en-us/library/microsoft.visualstudio.package.authoringsink%28v=vs.90%29.aspx
