+=item * part and project parameters as numbers
+
+Add parameters to give part and project not with their ids, but with their
+numbers. E.g. (default_/override_)part_number,
+(default_/override_)project_number.
+
+=item * part and project parameters override and default
+
+In the moment, the part id given as parameter is used as the default value.
+This means, it will be used if there is no part in the time recvording entry.
+
+The project id given is used as override parameter. It overrides the project
+given in the time recording entry.
+
+To solve this, there should be parameters named override_part_id,
+default_part_id, override_project_id and default_project_id.
