Yes, you load up a HH and you can then click on any qualifying hand (I usually go down to whenever I have 10BB or less to start with), and go hand by qualifying hand to see where you could have pushed/called and it would have been profitable...or where you shouldn't have pushed/called.
I personally use PT and PAHUD during my SNG play. If I was only an SNG player, I may not have bothered with PAHUD, but I had it for cash games and have started using it for SNGs. I personally find it very useful in helping me make some close decisions.
