Edit DOpus context menu

After some searching, I think it will be faster to simply ask: How do I create a 'context menu' entry for the DOpus context menu?
The Windows context menu has a useful entry to Edit TXT files using my UltraEdit text editor.
See screen clip:

The context menu for DOpus does not include this entry (since it is a Windows context entry and I have set "Hide windows file items on context menus"). I do want to make a shorter context menu, but I DO want this verb to be in the DOpus context menu.
I tried to add it using the context menu editor.



However, it does not show up on the DOpus context:

What am I missing?
(for now I just use Shift-Right click to get the usable context menu).
Thanks.

Creating a context menu with the type set to "Run an application" makes a Windows-compatible entry, which then ends up being hidden along with the other Windows context menu items. Instead, set the type to "Run an Opus function".

Thanks! That was the missing piece; although you can't change a context entry type, I created a new one that works.
Yeah!
