It is not currently possible to modify the “Domain overview”, as it is automatically generated. Changing the behavior of auto-generated items would require additional manual changes to your installation, which we do not support. Such changes may cause problems during upgrades.
Lansweeper version 5.0 will merge the web and configuration console and will work with widgets to give you much greater control over what is displayed where in the web console. We do not yet have a release date for Lansweeper 5.0.
