Could you please tell what particular service from PRT do you mean? If it’s pub.prt.admin:suspendProcesses then it’s not what I think is needed here because the service operates on process model (not instance!) level, i.e. you’d freeze all instances of the specified process model.
wM implementation of the BPMN notation is not complete here. I think such need can arise rather often, and there is a dedicated element in BPMN for this, which is not implemented in wM. It’s a pity since wM claims to support BPMN (well, not 100%, but still) since wM 8 which is a couple of years old now, and they still do not support this element.
Another element from BPMN which I personally have missed a couple of times is the event based fork.
UPD: Ah, you probably mean the service pub.prt.admin:changeProcessStatus? It could be used indeed. But I still think that the overall implementation would much more complex than it should be with a BPMN implementing product.
