Adding a custom Sub-Menu in DOC

Hi all,

Is that possible to add a custom “sub-menu” in DOC? Let’s say, something like: “Scenario” > “My Custom Sub-Menu” > “My Custom Action”?

I could only find in the examples a way to add an entry directly in the main menu (e.g: “Scenario” > “My Custom Action”).

Thanks in advance!
