This feature is available only inside the professional version of Domus Organizer
Sometimes an agency has a special need: maybe it has to load extra data from external tables, or wants to store additional information.
Usually you should do something Very Very Bad™: hacking the component. This is a short-term solution, because when a new update is released, you only have to options:
get stuck with the current version, missing all the new features
update and then manually re-apply the hack, hoping you didn't break anything
As you can see, in both ways this is a very bad scenario, however, do not be afraid!
Inside the professional version we added support for integration plugins, so you can add all the features you need, without hacking the core.
