What part of the event do you want to create dynamically?
One way to work around what you're trying to do is create a scheduled event that triggers every x minutes/hours. In that event, you retrieve all objects of "renes_scheduled_object". If there are none, don't do anything. If there are y of them, handle the work that's related to those objects and delete them.
If you really want dynamic Microflow invocation, you could even include the name of the microflow that you want to call in the object and fire it via a java action.
That is not possible.
