In the new app version 2022-12-12 released today, you can click the automation button to pause it and click again to resume, and any recordings, videos or tempos that were started by the automation track will be paused and resumed.
For the scenario described above, I think you would need to break the backing track into two recordings, the first one ending with the cymbal crash and the second one played from the automation track a few seconds after the first is done. Then you'd pause after the cymbal crash fades but before the second recording is played. But you might need to start the second (outro) recording manually from the Multiple Recording Buttons instead of from an automation track to get the timing right.
