[aprssig] New APRS Icon?

[Paul Fenrich]

I am new to the APRS world.  I have carried a tracker twice and I am 
building one now (nearly complete).  I have used them mainly for special 
events where radio amateur communications were requested.  Bicycle rides 
and foot races.  This year I was the "turtle" in the MS150 ride from 
Houston to Austin.  I thought how cool it would be to have a couple of 
special icons to represent the hare and the turtle.  Two important 
points of an event.  I looked through the Library of icons and don't see 
one.  I did notice there were several spaces reserved for "future use".  
Is it possible to add them and how can it be done?

Thanks,
