Is there a way to append items to the default intellisense list while using VBSyntaxLanguage?

Hi,

We are using "VBSyntaxLanguage" in one of our projects and we are getting the intellisense, however, we have a specific requirement to add new Properties/Fields to the intellisense list which are not defined locally in the editor. Is there a way to append new items to the VB intellisense list?

I tried inheriting the "VBCompletionProvider" class, but I couldn't get a hold of the intellisense List to append new items. I could able to bypass the default intellisense prompt by overriding the "RequestSession" method to create a new custom intellisense prompt, however I want to leverage the existing functionality of VBCompletionProvider and hence the question.

We are using Actipro Version 11.2.0551. 

Thanks,
Ram.
