I would also love to see this implemented, or at the very least, the ability to create sections and apply masters based on a place in the text rather than the page. Perhaps use an anchor in the text that denotes what master is used and what pages a section starts on so as the text moves to a different page, the master and section stay with the text. I do typesetting for clients in addition to typesetting my own books. I can try to not assign any sections before I'm 100% sure of the style, but there are times when clients request style or font changes, which can completely throw off all the masters and sections. Of course, being able to apply by style as suggested above would be even more desirable!
