Updating the Manage Account page custom tab
If your agency has set up a custom tab for the Manage Account page, the information on that tab will be read-only when you first load an account. To edit this information, click the Update Custom Tab link under on the Maintenance tab. This link can also be displayed in the panel on the Summary tab.
When you click this link, the Edit Custom Tab dialog box is displayed. You can use this box to edit the custom tab information and save your changes.
