how to move services from "services" sub context menu to main context menu?

I've been creating services (bash scripts) using Automator. When I assign services to context menu (from Settings -> Keyboard -> Services), they all appear under "Services" sub-menu in the context menu. I would like to make them appear directly in primary context menu so that I don't need to go through another menu to activate services. So I'd like to make them appear on same level as e.g. Move to Trash, Get Info, etc.

Thanks,

Jani
