It is possible to change the inheritance mode of properties when creating a global property.

It is possible to set this mode to append for strings and lists using the maa mode.

It is possible to override a global property in a specific agent or group.

When overriding this property in the interface, the default value for a new override is the inherited value.

This is perfect in override mode, this is acceptable in merge mode for json object, but this breaks the value in append mode (the new value will duplicate the content).

The default value should be empty if the variable is in append mode (easy for strings, it would be nice to have it for JSON variables that are pure arrays)
