I've tried various combinations of attributes for the first line and hanging
lines, and have experimented with bullets. I thought I once had a set up
that would do what I wanted, but now I think I may be mis-remembering, and
it just isn't possible. This is what I would like to do. This format would
suit my purposes in a number of situations. Could someone either verify
that it can't be automated with Word, or else tell me the steps to do it?
Note - I'm sure that at some point entering a return + dash in such a
document would automatically line it up under the preceding dash.

Abstract description of format:

Label with no indentation some sort of symbol, like a dash first line
of text, one space away from separator
remaining lines of text indented to line up under first line of
text
separator lines up under separator
