What is the desired functionality that you are missing?

As an Optimize user I would like to be able to create Event Based Processes based on multiple camunda processes. In this use-case I would like to use the full process diagram from each process and Optimize should automatically chain the diagrams.

If automatic chaining is not possible, alternatively I would like to place a full diagram of a process with complete mapping to a BPMN.JS canvas and manually link the start & end events of the shown processes. 

This would speed up creation of a complex Event Based Process tremendously. 

Which problem are you going to solve with this functionality?

Today I have to manually map all of the events of Camunda processes to steps on the diagram. For complex processes this is very time-consuming - e.g. having 50-100 Acitvities in the process. Optimize already has this information and should be able to at least place the separate full diagrams including mapping onto the canvas.
