How to retrieve information about sub processes from a parent process in jBPM 5

Issue

• In business central, I can see my main process and reusable sub process as individual entries in Processes section. I can't tell which sub process instance was kicked off from which main process instance. Is there a way to find that out from the console?

• Also, I would like to find out programmatically what the sub process instances are for my main process instance and if I am a sub-process instance, who my parent process instance is. Is there a way to get the above information programmatically?
