Reuse Sub Assy Explode States in a Top Level Assy

Creo Parametric 2.0

I am trying to reuse the explode states I defined in my sub assemblies when exploding the top level assy.  I thought there was a way to do so, but I can't remember how or I'm mistaken.  I may be thinking of style states.  A year away from Creo has taken its toll on my memory of some functions.

Thanks.

(Interestingly, when searching I discovered that I had asked this before, almost 10 years ago, evidently with no response. That or the response was lost in one of the great community migrations of old. 😁)
