following areas accept custom values in the link (destination):
Dashboard Shortcut Buttons
Custom Menu Items
Quick Action Items
The name portion cannot be powered by a custom value.
If a custom value does not exist for that particular location, the item or button will not be visible.
How this is Useful
In this way, you can use one set of menu items, buttons, etc and when that feature or report is enabled for that client, you can then add it as a custom value for that location.
