We recently launched a premium feature that allows you to map a custom space usage label to our default usage label menu in your account interface.
With an admin account, go to your Organization page under Account;
In the Space program section, click on the "Custom label" cell and type in your preferred name, then click "Save settings".
You will see the updated label appear in all of your models.
