Identifying the Backlog Plan breaks inheritance model in Rational Team Concert

In Rational 6.0.3 we now have the ability to identify a Backlog plan per Timeline.  This is most needed for Quick Planner.  When creating additional timelines, if the Backlog plan is not properly identified as the 'Backlog' for the timeline when using Quick Planner, the Backlog plan doesn't show up.

All of our RTC project areas inherit from a Master Project Area.  Using the new feature to identify the Backlog plan breaks the inheritance.  It resolves the issue of a Backlog plan in new timelines showing up in Quick Planner but we do lose that inheritance.

Is there any work around for this?  We would like to keep our inheritance model and provide the ability to use Quick Planner with multiple Timelines with a Backlog plan per Timeline.
