11i Consolidation Set up Issue or functionality limitation?

We are on 11i and we have a consolidated set of books.  At this time we are no longer using it  due to consolidation issue or functionality limitation.   Here's the deal.

We have 4 sets of books ( 3 sets in each functional currencies) and a consolidated set of book.   Once we close our  functional books then we  move over the data to consolidated set of book. However,  there are some instances that we need to open the functional books again if we have a material adjustment that we need to record.  The issue is that we can no longer bring over the  additional entries to consolidation set of book since we already performed the initial consolidation, is this a set up issue or functionality issue in 11i? I would like
