How do you add options to the Right Click Context Menu when nothing is selected in Finder in OSx Mojave?

I am wondering if it's possible to modify the Context Menu which pops up when you right-click on nothing in particular in Finder (shown below on the right-hand side)

I have no trouble adding options to the context menu which pops when you right click an item (left-hand side)... but is there a way to add options to the menu on the right-hand side?

For instance, could I add a custom option 'New Majig' below 'New Folder'?

Further Info:

In case it's useful, here's how I'm creating the options I want to use:

1. I created my custom options in Automator > Quick Action, like so:

2. And then I added them to the context menu in System Preferences > Keyboard > Shortcuts > Services

I am in Mojave 10.14.2
