Create a Top Menu item not bound to category - Prestashop 1.7

[Proteas]

Hello,

Let's say I have 7 main categories of products. I have the first 4 main categories appearing normally on the top menu, but I want the last 3 main categories to appear as sub-items under a menu named "More" or "Extras".

I don't want to create a main category named "More" and put those 3 main categories as sub-categories. I just want to create a top-level menu named "More" (that does not correspond to any category ) and insert those last 3 main categories as sub-menu items under it.

Is something like this possible in native Prestashop 1.7 Main Menu addon?

Thanks
