Is it possible to display all of the Service titles in the context menu?
To show all Services on the Context Menu in Finder, do the following.

In Terminal, use the following commands:

defaults write .GlobalPreferences NSServicesMinimumItemCountForContextSubmenu -int 100001
killall -HUP Finder


Now all applicable Services in Finder's Context Menu should appear without being in a Services Sub Menu.

To revert to default behavior, use the following commands in Terminal:

defaults delete .GlobalPreferences NSServicesMinimumItemCountForContextSubmenu
killall -HUP Finder


Note: I've only tested this in OS X 10.8.5 and OS X 10.11.6 and it worked in both, so I'd assume it should work in the OS X versions in between. I've also tested this it in macOS 10.12.2 and it works, so I'd assume other versions of macOS 10.12.x it should work.

Update Note: This should also have an affect on other Context Menus in Applications other then Finder. However, applications that are running at the time this change is made must be restarted for this to take effect. After this change has been made, applications opened afterwards will be affected immediately.  You can also just logout/login for the change to take effect globally, all at once.
