Brisk-Menu session management buttons (Logout, Lock Screen Shutdown)

Hi,

Please can someone point me in the direction to change the brisk-menu session management buttons. Ultimately I would like to be able to remove lock screen and shutdown from the options.

Here you can modify what is seen.

    System, preferences,look and feel, main menu

Hi, thank you very much for the reply - unless i am missing something obvious (possible!!) i cannot see the options to manipulate the session management buttons in this menu editor. I took another screenshot to better highlight the area in question...
