Sequential multi-instances?

How can I show the sequential multi-instances on task/subprocess? There is the parallel multi-instances in the type of loop list but not the sequential one.

Click the … button next to the loop type, the spec has a field “Ordering” where you can select parallel or sequential. :-o

The sequential multi-instances is not part of the loop type, there is the standard loop and the parallel multi-instances loop. No sequential multi-instances choice, neither the icon.

And it is not BPMN-compliant to absolutely select the “integrated process” to show the ad hoc choice (and by the way, this way there is parallel and sequential but choosing sequential doesn’t give the right sequential icon as we have in BPMN).
