Saving a New Item When It Is Not in the "Prompt With List" Action

[JMichaelTX]

I'd like help with - when the user's input can't be matched in the list then take the user's input and put that in a separate variable so it can be added to the list and used as a tag in the current document.

Perhaps the best solution is to modify this macro by @DanThomas:
MACRO: Spotlight Search Prompt . (which has nothing to do with the macOS Spotlight search)

We discussed that very feature in the above link.
Actually, I don't think it would be that hard to simply add a button to Dan's search to "Add Item" using the current typed text.

My preliminary thoughts on doing this suggest this workflow:

1. Type a string in the Search box that is NOT found in the list
2. The "Add Item" button (and shortcut) are enabled.
3. The user clicks "Add Item" (or presses the shortcut) to close the search and the string that was typed is added to the source list for the search.

Comments or suggestions on this?
