Add requirements with custom stereotypes to Extended Requirements Toolbox

[etaha]

I need to define requirement with highlevel stereotype and add it to requirements diagram defualt toolbox.
I think this requires MDG profile creation. I've explored its documentation but I couldn't make requirement as metaclass and add highlevel steroetype. Available metaclasses are only UML core elements. How to add meta class of a requierment to MDG profile?
Thanks in Advance.

There will be a checkbox named Include Extended enable it and use extended Elements.
