Change actual export filename of text-to-speech audio from Timeline?

I need to export all of the neural TTS mp3s I'm creating for the project for archiving. I can easily rename them in the timeline, but that name doesn't actually change the filename for export from MediaLibrary , which is something like "text-to-speech1-mp3" by default.

This means that I need to rename about 300 files manually in a giant list, listening to each one and trying to match it to the correct slide name.

The only ting that makes this easier is the fact that when I click the "used on" number for each file, the viewer jumps to the right slide.

Is there an easier way to do this?
