In Office 2010, I created a Normal template with certain styles. I then created other group templates based on the Normal template. I want to update certain styles in both the Normal template as well as the other templates. How do I do this? I believe also want to change all of my styles to check off "New documents based on this template". What exactly is this option and is there a way to modify all of the styles rather than having to modify each one in each template?
