Configuration of combined attributes

In ARIS standard method there are for example document links combined with a title. Since that we need more then four pairs of attributes Title 1..4/Link 1..4, it shall be possible for the configuration administrator to define such attribute clusters for custom defined attributes. We would need additional attributes Title 5..6/Link 5..6 with the same behavior as the standard attributes. Otherwise it is not possible to handle and show the new attributes the same like the existing ones.
This was once addressed as SI-515701 but closed without a solution.
