It's easy to toggle segments on or off to make them available or hidden from your team when they assign accounts, classes, departments, etc. to their charges
You can deactivate unused segments by going to the Settings tab and then selecting Accounting and Settings.
Once you're there, you'll be able to see your segments and make changes. Just click on the segment you'd like to hide, and toggle the option track to the left to hide it from your dash. This way, you can keep your dash organized and only display what you really need.
