Extend query on relation behavior 

From a relation behavior config file like this

status:
     label: Status
     list: @/plugins/path/to/your/relation/config/columns.yaml
     emptyMessage: backend::lang.list.no_records

You can extend the list query with this method :

relationExtendQuery($query, $field, $manageMode)
{
     if ($field == 'status') $query->where('thing', '=', $this->thing);
}
