On a call activity, I can jump to the child process before it is executed

[saig0]

Is your feature request related to a problem? Please describe.
A call activity references a child process. If the call activity is activated or completed then I can jump to the child process instance.

But only if the call activity is activated or completed.

Describe the solution you'd like
From a call activity, I want to jump to the child process. If the call activity is activated or completed then it jumps to the child process instance, as it is now.

Otherwise, it jumps to the process that will be called from the call activity. The child process could change over time if a new version of the process is deployed.

If no child process is deployed then I can see a warning or note. I could remind me to deploy the child process before an incident is created when activating the call activity.

Describe alternatives you've considered
None.

Additional context
None.
