Default Re-Intervention Time

Please add an option to set a default Re-Intervention time (e.g. 10 min), so users don't have to manually set it each time.

This should be combinable with delayed interventions, allowing scenarios like: using the app for 10 min (delayed intervention) before the initial intervention, then automatically triggering another Re-intervention after the preset Re-Intervention time (e.g. 10 min).
