Ability to restore dashboard via a Trash/Archive

We would like to have a feature to restore from trash/archive kind for the below scenarios.

• Recently, we have encountered many support cases where the dashboard gets deleted when a user leaves a company due to the site access revocation/user removal from the site.
• We are also seeing issues due to an accidental deletion for dashboards/shared dashboards.
• We do not have an log traces generated if some users deleted a shared dashboard from Settings > System > Shared items > Dashboard so even if the deletion happens at customer end, we are unable to proeve the same and customer asks for retrieval in such cases if we cant find the actual user who performed this action.
