Restrict viewing of linked processes in the output /input when sharing Minimode link

Is this a bug or an improvement request - minimode sharing correctly restricts access to sub-process links; however, process links found in the input/output are freely available.

When sharing minimode link we only want the external users to see that specific process information only (including the linked documents). However, any links to any processes should give the user an error message that they do not have access.
