Can you make a document automatically update changes styles template?

I'm making a change to my workflow, so the body text will have its own, well, "Body Text" style, and the "Normal" style will be reserved for use as template for other non-body text styles.

Having made the changes in one of my manuscript, I've copied these new styles to the Normal.DOT. But when I open my other manuscripts, these style changes in the Normal.DOT are not dynamically reflected in the documents based on the Normal.DOT. I have to import them into each document from the Normal.DOT.

Is there a way to make this happen automatically by option?
