Custom Slide Breaks

I like the feature that allows me to set the number of lines per slide, but it is for the whole song. Can an option be added that allows the user to determine the number of lines for each individual slide? Some songs have verses that naturally break after 4 lines while the choruses split better into 3 lines per slide. I have to cut and paste lines to help the flow when this occurs.

In edit mode, there is a button under formatting that will set a maximum number of lines per slide. if there is a way to just type in a number of lines per indivicual slide, it is hiding from me. If you press whatever gets re-used for alt on a windows keyboard (Option on Mac?)+Enter it will insert a slide break instead of a line break.

Thank you. I also just found Alt + Enter at the bottom of the Keyboard Shortcuts. That works well!
