Here is my situation. I have an existing document which has existing
Normal Template styles implimented throughout. I took some pieces of
example text from this document and put them into a new document.
These example texts include an example header, sub header, and text (I
am keeping this simple for now). I save this new document with the
example text as a template. Then, I define new styles for each example
text based on the style the text was already using. Once the new
styles were created, I made sure they were applied to the example text.
I saved the template. Now, I open the original document I pulled the
example text from, go to Tools Templates and Addins and 'attach' this
new template to the document. I expected the styles in this new
template to overwrite the old existing styles in the document, but that
does not happen. The only thing that happens is that the new styles
are available to use in the document (which is great but not the result
I was looking for).

Is there anyway to attach this template to the document so that the new
styles overwrite all of the old styles they are based on in the
document? I have searched and read everything I can find on this, and
it sounds like it should work the way I am doing it, which means I am
probably missing one small detail that is crucial for this all to work.
Please help me!
