Add Modules to current doc's template

Question

I've got a working set of modules in VBA that tag tables as required by Government Printing Office guidelines. The code consists of a form and one additional module, plus one macro in the 'NewMacros' module that serves as an entry point to the form. We receive documents from external sources with no table coding or perhaps one table out of many coded, so I need to allow our local users to code one table at a time. Question: How can I either do this from .NET or insert the required modules and a small task bar into the current document from .NET? Thanks in advance for any suggestions.
