A common use case I seem to have is to group related fields for re-use into a common content type, and link it with a Reference field.
For example…
LinkListItem:
url
text
LinkList
items: [LinkListItem]
Reference fields have 2 options, “Create new”, and “Link Existing”. I don’t ever want a user to “Link Existing”. I really only ever want them to create new. As a configuration option, I’d like the ability to simply configure a toggle that says “I only want a user to create new entries here, I don’t want them to link existing”.
And bonus points if I can have control over the button text… instead of “Create existing”, i’d like to configure the text to say “Add item”.
