Next Page Custom Title

Is there a plugin or hack in order to be able to add a custom title to each page break in a post.

At the moment I use <!– Next Page –> and whilst this works I want to be able to add a custom title to the Button.

e.g. Instead of ‘Next Page’ I want it to read ‘Next Page: Features of the Product’ and Next Page: Price of the Product’ etc etc.

Any help appreciated.
