Custom drum notes

[Mike J. Bell]

I'm putting a "fingering" above a tom-tom in drums mode:

\version "2.12.3"
\drums {
  % note that ^3 doesn't work with drums
  sn4 tomh^\markup { \small 3 } sn sn  
}

I'd like to make it so EVERY time I do tomh the 3 is printed in the fingering above the note.  (Or, we can call it something new if I shouldn't or can't change the definition of tomh).  Can someone point me in the right direction?

Thanks a bunch!
Mike
