Combining Schticks?

New GM here, drawn to Feng Shui 2.

The question I had, brought up by a player, was this: can a player combine their character's schticks into one attack?

I don't see any sure answer in the book, so I am unsure of the answer I gave to that question. I am guessing, and what I replied to the querant, that any schticks that are based specifically upon making on a successful attack may be used as part of one of a character's shots during a sequence and are not combined and stacked with others. Several schticks seem to always be "on", like Hands Without Shadow, and thus could be used with one other schtick that can be used on a successful attack.

Am I right on this, or am I not seeing something?
