Using Suggester for uncreated links/notes?

[SteveDockar]

Brief backstory: I often include the names of people in notes using [[First Last]]. I don't usually create the actual person/linked note but can still see the "person" in the Graph View with the "Existing files only" filter disabled. For people I deal with often, I like to modify the link to [[First Last|First]] so the note looks a little more personal and less formal, but if I do create them, the note file will be their full name for clarlity. When I do create a person file, I add "First" as an alias so this is more automated.

I created a QuickAdd to capture "First Last" using inputPrompt and then use Javascript string wrangling to return "[[First Last|First]]", but would like to enhance it to allow me to pick from existing uncreated (people)notes like typing [[<some-text in the note editor does. I managed to get the example suggester API to show existing note/files in the vault, but couldn't figure out how to access Obsidian's resolved and unresolved links (or anywhere else I can get suggestions from). I had a cursory look at the Obsidian API docs, but that's way deeper than my current level of knowledge.

Is something like this possible, and if so have I just failed to spot the helpful example or is there (much) more to it than that?

Thanks in advance.
