A style contains the indent setting.
So that can’t be ideal, because you can only set one indent per style.
That leaves you with three options (in order of convenience, my POV) :
1- Use the list feature instead.
. . . . . . .
2- Set the TAB values as you want them for a paragraph, and create or redefine a paragraph formatting or save all formatting style from this paragraph.
. . . . . . .
3- Use one style per indent/level.
…I don’t recommend it so much (use that if there is more purpose to the choice than simply indenting what in the end is simply a list), but here is a template :
→ The only advantage of this over TABS is that tabs don’t work in an Ebook, and that using this multi-styles method, you may have different fonts and whatnot per level.
