Two fingerings on same note

[David Rogers]

Hi

Version 2.7 on Mac OS X

I'm printing an exercise for piano that is to be used by each hand  
separately, but reading from the same notes. I know how to put right  
hand fingerings above and left hand fingerings below, when they're on  
different notes:

fis_1 a^1

but what about the times when I want the *same* note to have a right- 
hand fingering above, AND a left-hand fingering below?

Thanks
David
