Framemaker book asking me to relink to deleted graphics for any file within book where graphic once

Hi - 

I have a specific question but I have to imagine others have had it happened. 

Currently working on FM2020. All software is managed by IT, so I cannot download any extensions/extras/or change my FM SW, just as a note. 

The issue: I work on big user guides (400+ pages) and include many images of our app and physical product in workflows. When software is updated, screens get updated. When designers make a change, design elements on the GUIs change. When I put updated GUIs/artworks/button graphics/whatever in my links folder where I store them, and then update the image in the book file, save, close, then reopen the next time I have work to do, Framemaker asks me to update the path for the image/element that is NO LONGER in the document. I delete these images/elements from the links folder. We have so many, and also translate into multiple language from our English source, it is not practical to hold onto not in use images. 

Has anyone encountered this? This might seem minor, but when I'm swapping out 20+ images and having to "Ignore missing file" every time I open all files in a book, it becomes extremely burdensome. 

Any advice??

Thank you!
