Invoking Index Shares

May I know how to Invoke the BSE 100 and NIFTY 50 listed shares in PI ? I am not able to find this option in the Menu Bar.

Goto file-> predefined work-space-> NSE and select the required one. But before that make sure scrip count of 250 is selected by going to view->user setting-> market watch-> under scrip count select 250 instead 50.
