Feature request: Archive/remove backup jobs or servers

Once a backup job has sent a report to Duplistatus, it's added permanently (along with its server). If this backup job (or this server) stops being used, there is currently no way (that I can find) to delete/remove that backup or server from duplistatus list: it shows as late.

Could you add a way to archive/remove from view/delete from database individual backups jobs, and servers?
