Close flow from verb sub-task. Flow classic 6.14

Hi!
I’m struggling with a flow that is built using a verb sub-task structure, and I would like to have two different end steps.

  • One end step should return control to the parent flow and allow the process to continue

  • The other end step should fully end the flow and close the session.

Is this possible with verb sub-task flows?

A workaround might be to set variables as output and let the parent flow decide what to do next, but I would really prefer to terminate the flow completely if possible.

Thank you in advance!
