You would need to extend the default file: link completion function -
`org-link-complete-file'.

You can override it with any custom function:

(org-link-set-parameters "file" :complete #'your-custom-completion-function)

It is, although even more common request is simply inserting a link to a
heading in _a_ file (not known).
