A Line Break or Visual Line option to visually separate different sections in a list

Lists can become a singular block of text when they grow quite large. For example, a list I compile can have sections to denote the main document, research, and line items already processed. I’ve started creating lines with the text ‘----’ to break up sections and create a bit more visual clarity.

It would be great to have this as a feature - either a line break that creates a gap between sections or a line that inserts as part of a bullet point to visually show a demarcation between two sections.
