Hi Chris,
Unfortunately title/content matches during the fill process are not possible without completely re-writing that code section. I checked if there is any modification I could suggest, perhaps replacing a file, changing a few lines here and there, but it is a bit more complicated than that in terms of coding. Showing the post matches on the editor screen would be even more difficult than that, as it needs a complete implementation from the bottom to the top. I have noted these as feature requests, and will try to include them in an upcoming release.
