Without a lot of re-coding work, that's not going to happen.
What you could do, is use either the original or modified form of the macro (depending on whether you want the code to apply to the whole document or just a selected portion) and add the following:
.Style = "Normal" (or another style name of your choice)
before:
.Format = False
which you change to:
.Format = True

That should make to code reformat only the text in the nominated Style.

PS: I've got very limited internet access ATM, and won't be able to respond to further queries for around 10 days.
