You can create new column items to include custom properties for objects when displayed in the tree view.
To configure the column set items, right-click the column set, and click Manage Column Items on the shortcut menu. The Manage Column Items dialog box appears.
There are two tabs in the right pane, Library and Navigate Schema. You can create or add column items to this column set using either tab.
