Add possibility to edit the titles of entries when using "entries" field in blueprint (just like navigation works)

This comes from Discord thread: https://discord.com/channels/489818810157891584/489818810157891586/threads/1213071076838346812

Add "entries" field to blueprint where the titles of the entries are editable. Just like how navigation works right now. This makes it easier to create a block of entries with links and use custom titles. The only workaround now is to misuse navigation for it or create a grid with title and urls (with the con of entries not actually being linked since it is just a url).
