Sorry Guys,
It is actually Individual Customer, not Lead. But I'm assuming it would be the same, am i correct? 
Edited Version:
I'm in a situation where i need to hide the Standard Overview for Individual Customer, and Create my own Overview that will show Tickets, activities, campaign, survey and marketing interaction in my Custom Individual Customer Overview.
I had hidden the Overview of Standard Individual Customer using the Adaptation edit mode in UI5. However, can i know how am i able to create my own tab of Overview and show all the listed summary of tickets, activities, campaign, survey and marketing interaction in my Custom Individual Customer Overview so that the user don't have to go to the tabs and view it one by one.
Please Help 
Thank You.
Regards,
Richie
