I've been tinkering for the last half hour or so and have not only figured out how to solve my provlem but also realised that I initilly phrased my problem incorrectly. It's actually the list style that I wanted to save and I was constantly saving list formats as paragraph styles. I realised that I (and this is the reall unintuitive part) had to hold the button with a plus and a little downwards facing arrow on it at the bottom of the styles drawer to reveal a menu of different styles to create; paragraph styles, character styles and list styles. I realised that to save the list format that I specifically wanted in all of my documents, I had to create a new ilst style rather than a pargraph style. Thank you anyway for your help!
