Can I define a hybrid stateblock in an MDG and have it appear as a single thing?

[Roche Pso]

I suspect the answer is no, having read a few older threads, but this is just to confirm it isn't possible:

In a profile diagram I have created a stereotype called stateblock and used it to extend a state metaclass and a class metaclass, and have generalised it to a sysml block stereotype. With the hope I could then have a hybrid stateblock to use in my model, for reasons.

When I create the mdg and import it I end up with the ability to use a block with type <stateblock> or a state with type <stateblock> but both things are still 100% block or 100% state and not a hybrid object of both types.

Is it possible to create this stateblock type by some other method?
