It is possible to set up a multilevel list with right-aligned numbering, but some trial and error will be required to get the indentation around numbers correct (as I stated in earlier replies).

If you want a hanging indent for each level, the "Text indent" setting for each level must be equal to "Add tab stop at" at that same level, and the specified value must be larger than "Aligned at." I believe that Charles covered this in one of his replies.

Personally, I find that putting the numbers in the margin looks better with right-aligned numbering.

With an indented list, left-aligned numbers are a bit easier, but right-aligned numbering looks better, once you have got it right.

Good luck, whatever you decide to do. :-)
