New screen with table control information in Process Bid Invitation

Experts,

This is again a similar requirement as my earlier post today. We are on SRM 5.0

I need to add a new screen with table control information in Process Bid Invitation.

I need to add the new screen under Item Data tab.

I need to name that screen and that name shud appear on top under the Item Data Tab as a link to that screen.

( Typically like what we have for

Header data

Basic Data | Partner | Bidder/Bids )

How to go about this?

Any help on this regard is appreciated.
