Hi Anna,

TauP has a utility called taup_setsac, it inserts a theoretical travel 
time in the t0-t9 sac header values, and at the same time it inserts the 
corresponding ray parameters (slownesses) in user0-user9. I've never used 
it for this latter purpose, but assume it works. The taup documentation 
should help you further if you want to try it.
