Adding ZTcodes in Main menu

Hello Friends,

My client wants to add a new (Customer Specific) folder and subfolders which contains custom transactions developed for the project to SAP menu in ‘SAP Easy Access’/Main screen i.e Tcode : SESSION_MANAGER or first screen after login.

Can some help me in achieving this by giving me some steps on how to add addition T-codes to main menu?

Note: This should is NOT a user menu/favorites issue. They want to add these T-codes that can be viewed by all users and can be moved from one system to another system.

Thanks

Venkat
