Creation of Delta Depreciation Area through Wizard

Hi Friends,

I have Book Depreciation area(01), IFRS (11) and Book Depreciation area(Grp Ccy) (41), IFRS(Grp Ccy)(51) am trying to create 2 Delta Depreciation Areas (One for Local currency and another for Group currency). When I am trying create it through Wizard (Set up areas for Parallel Valuation), I am able to create Delta Area only for Local Currency (11-1) and I am not getting option to create it for Grp Currency).

I've attached screen shots of Depreciation Areas and Wizard.

I need an option to create 2nd one for 51-41. Can you pls give me a little idea.

Thanks
