When building a dashboard for sprints you will typically have several widgets tracking a sprint.
When the sprint is over, those widgets ALL need to be repointed to the new one. (This is particularly applicable when using a Label or Drop Down custom field.)
A better solution would be to have certain parameters for the dashboard manageable in a single place—not per widget.
Datadog dashboards solve this with Template Variables. See: https://docs.datadoghq.com/dashboards/template_variables/
