Here's a new kind of ASB I think might suit certain situations. Rather than dividing it by scene, it's exclusively by page number, so if you don't have scenes determined in your text, then you can have these. Also, depending on how your director works--maybe a more visual representation of how long actors are onstage is more useful to your director.
"The House of Yes" already has the scenes divided up, so it might not be the best one to use for an example, but it's a new template I'm developing. Let me know if you have any suggestions/something that could make it clearer/questions about the information.
