How to use Palm Pilot & Chess Tiger to practice tactics?

I just purchased Chess Tiger 15 for the Palm a few days ago,
and I think it's great.  Now I would like to find a way to
practice tactics using the palm and/or Chess Tiger.  Can
anyone recommend a way to load up a bunch of tactics problems
on the Palm Pilot?

I did find a .pgn file with all the problems from '1001 Chess
Sacrifices and Combinations', but I have to paste each position
one at a time into a memo, and then load that into the Palm.
It would be nice if there is a better way.  Is there any software
specifically for this purpose?
