We try to get comp descriptions updated where possible but sometimes (usually for laptops) we know what we want to put in the description but the laptop may not be accessible for sometime to make the change. Perhaps allow a manual description to be entered via the custom fields tab and locked?
A number of computer fields will be turned into lockable custom fields for Lansweeper 5.0. Lansweeper 5.0 is currently in development and we expect to have a beta release ready by October.
