Event creators and wait for local events

Hello gurus!

In one of our workflows we have the idea to call a local WF several times during the different stages of the main WF. The question is: how can i return the flow exactly to a point after the event creator step which called the local WF?. When i have just one wait for that WF there is no problem, but what happens if I have 4 possible returns? How can i tell the flow to go to a specific wait?.
