Hi,

I think this is entirely possible: you define your own engine that will 
control the criterion for stage transition (e.g. stabilization of the 
box compression) and if it is satisfied, it can do whatever it wants 
(including dispatcher additions/removals from rootBody) and then go 
ahead to the next stage. I think Bruno had something similar with his 
triaxial test?

And for singleaction, someone else knows better probably?

Regards, Vaclav
