Zapateado in Lilypond

[Peter Nærum]

I am trying to use Lilypond to notate Zapateado (footwork in flamenco). 
In the system I use, left foot is marked by a stem going down, while 
right foot has no downward stem. Notes have meanings like: f: flat tap, 
a: strait tap, c: heel tap, e: toe tap.  Besides there are two ways of 
using the heel: With the front foot on the flour and with the foot clear 
of the flour. The first case is marked with a dot in the a-position in 
the staff. I have included three small examples. Do any body have a clue 
if it is polible write these markings in Lilypond?

Thanks for any help
