WTH -- No option to perform Full Backup when updating

Currently, when performing an update, you have the option to Create backup before updating. That backup only backs up the specific thing you are updating. If you’re updating an addon, only that addon is backed up. If you are updating the Core, only the Cord is backed up.

WTH can’t we choose to perform a full system backup (Core AND all Addons)?

That’d be great, even if it were just offered for HA updates.
