Detect canceled ExternalTasks

[Firestorm87]

If an external task is canceled within the process engine, I as a client can only recognize this when I want to complete this task or extend the lock.

I would expect - at least during the period in which I have actively locked the tasks - to receive information about the cancellation in order to be able to cancel long-running tasks in the worker.

Unfortunately, I can neither discover the corresponding possibilities in the Java client nor in the REST API.
Is something planned here?

Best regards,
