underlining support for markdown syntax?

Hi list,

im looking for a posibillity for fast "underlining" some Text with a
charakter like "=" or "-", which is used in markdown-Syntax.

I.E. if I write some comment in a program like

# This is an big Headline
# =======================
#
# And this a normal headline
# --------------------------

So it would be nice to expand the "=" or "-" with a command up to the
end of the upper line.

How can I do this? Is there a builtin for this? Makro?

TfH!
Oliver
