Check existing/non existing files

[Former user]

Can LaunchBox check the existing files everytime I launch it? I am using No-Intro Redump Trurip databases for naming my files, I importing those manualy (one by one), but for example, when No-Intro changes something in database, the file name changes too. So, is possible that Launcbox always checks that (or ability to sync that with some button)? And if some of the file it can't find, the row of the list view turns red?
