How to change hex constant representation from 'h' to '$'?

[TimRegeant]

How would I get the listing window to show hex constants as $ instead of h?

ex)

dc.b $FF
instead of
dc.b FFh

On the old TI-99/4A the much rarer hex sigil > was used. It would be nice to have configurable and/or alternative syntaxes.
