The caption function in Writer is amazingly useful, and combined with indices such as Index of Tables and Table of Illustrations increased my productivity infinity-fold (previously had to do all that manually; not an activity to do if you like to sleep during thesis terms).
However, I was wondering if there was any way to make your own, the same way you can make custom Styles. I want to have a category for Figures instead of Illustrations, and I have to trade off productivity and proper formatting (in some courses in college, the label of such things like “Figure” is strictly applied).
