Usability of delegated UIs

One of the apparent limitations of the
delegated UI protocol is that the resource views offered to the user cannot
be adjusted according to the user's scenario.

For example, the user wants to make
a link between a requirement and a test case, and so must pick a test case.
 The RM application then makes a link to the selected test case. In
this scenario it would improve usability if the QM provider would not offer
for selection test cases which are already linked from the requirement.
This is a bit contrived but I hope it illustrates the issue.

Is anyone aware of previous work or
exploration in this area?  I am aware of the work being done in the
CM TC where configuration context may be used to inform the picker behaviour
(for example, filtering resources to those in the specified context).

best wishes,
