I join this request too, but with a bit wider idea:
it would be great to be able not only to link but to quote the previews entries as well, completely or in parts with an active link, and with date of this "old' text. Approximately, it could look like a quote on the forum.
This may require more complex text formatting, then probably it would be better to divide the text entry mode and reading mode (to be honest, it would be better anyway 😅 ).
