I see that you can create shots and there is a horizontal line situation but what about the traditional vertical lines on the page that represent coverage. Can story do that? Is there even a way to manually do it in story?
There is an option to insert 'Sound Elements' (in Production menu) in the script. These elements get added vertically to the right side of the script.
This could be similar to what you are looking for.
Here is some info about it:
