a possible use case is as follows:
Your manager wants to get an overview of the progress in the last month. Thus you want to depict the progress by using a report.
This report should show the items with their content from the past but their "confirmed by" links from today.
If you run a report on the items in the past (to obtain the Requirement's original content) the report would show that no tests ( Confirmed by relationships ) have been executed til now. This is due to the fact that the Requirements were not tested at that moment in the past (certain Label). That's why I want the Confirmed by relationship from now (today) because some requirements have been tested over the last month (Confirmed by relationships exist now). By doing that it's possible to show which and how many requirements have been tested over the last period.
If you run a report on the items from today, you receive the current item's content (Requirement's content). Probably these contents are different from the original ones' because another divison is working on these requirements and developping them meanwhile. The report would show different requirements and more important than that, no executed tests. On the one hand the test cases refer to the same ID, but when the item's content has changed over the last period the test is automatically in "execution mode" (even if it's passed or failed in a past state, actually).
In a nutshell: Is it possible to write a report that shows an item's content from a past state but its "confirmed by" relationship from today?
