Cast Sequence Macro?

[VyneDono]

Hi, guys. I'm trying to make a Cast Sequence Macro for my Windwalker Monk.
Basically, all I want out of it is to cast Jab, and then cast Chi Wave when it's off CD.

My current macro is:
/castsequence Jab, Chi Wave

However, if I try to cast Jab again while Chi Wave is on CD, it will put the entire Macro on CD. This is extremely detrimental to DPS, obviously, so I can't use this. Is there a way to make it so that the macro never goes on CD while still doing the function I want?
