Question regarding ChordNames

[John Helly]

Aloha.

I've got a guitar leadsheet that displays the guitar chord G# as Ab.  
For me, it's more natural to read G# and I would like to change the 
ChordNames to a preferred set but I can't find the (a?) description of 
how to approach this.

I found some Scheme code to get rid of double-flats and was able to 
implement that (I'm also using \transpose at times on this score) but 
can't figure out how to change the enharmonic mode (?) from flat to 
sharp on a chord-selective basis.

Any guidance would be appreciated.

Mahalo.
J.
