Tips for implementing command supers into your play-style?

Been playing Savior since Resurrection came out and feel pretty comfortable with it,
but I’m having a hard time implementing command-supers into my game,
so I was wondering if people have any tips on shortcuts, timing and such for using them effectively?
Some characters like Hsien-ko is pretty easy to get but with others like Lilith, I pretty much can’t combo it except from close HK which is a big problem since she apparently revolve around using LI.
