Hello Avadh,
I dont think this is possible. how ever you can give it a try.
go to SE80 t-code and open the BSP Application "crm_ui_start".
Next "Pages with Flow Logic' and double click on "Default.htm".
This is the page which gets loaded when you use "crm_ui" t-code.
But this is a SAP standatd BSP page which will not allow you to do any changes.
Br,
