Workset Question for EP 6.0 SP2

I have a delta-linked workset within a delta-linked workset associated to a role. How can I make the content of the second-level workset appear expanded, by default, under my Detailed Navigation iView? By expanded, I mean by automatically showing all pages or iViews within the second-level workset. We are currently running SAP EP v6.0.2.3.3.

Thanks,

Fernando
