Automated Lead Tracking Alerts for BDR Managers

Hi team, Quick question - We assign leads to BDRs on the CRMs - how are managing automated tracking for the manager? For ex. If leads from one particular source were assigned a week ago, how can we set some alert after a week that now it's time to check for updates, without bombaring the manager with individual lead-level notifications. Ideally just one alert for the same.
