I've done that with matchsticks, so I know it works.  You just need to 
know which of the "fingers" on the unit select to emulate.  If you can't 
get a spare "1" indicator, I'll go and look at mine to see where the 
matchsticks would need to go.

I eventually made a whole set of indicators (0...3) out of perspex.
