Can I add wait state in BpmnParseListener?

I want to add wait state after service tasks of certatin java delegate, without having to explicitly add wait state like task/message when non-developer drawing bpmn, is it possible?
I already did learn to add AbstractBpmnParseListener for adding async continuation, but still couldn’t figure out how to add wait state, which actually make process engine to wait.
Scenario: some of my service tasks are always followed by user tasks that always configured the same way.
