Im actually looking for the same feature. Ive tried to find other plugins that might work but so far this one is the closest.
Also it would be much more user friendly if you were able to insert the links from a button on the TinyMCE like this plugin https://www.ads-software.com/plugins/post-to-post-links-ii/ (only having them pop-up in the modal, and preferably on hover ?? )
