Copy Filename to "Title" Metadata Field

I found this same question is the legacy discussion board for Capture One 8, but there was still no answer for this one so I thought I'd throw it over this way.

I'd like to find an automated way to copy the filename of each image into the title field without doing it manually for every image. Because of the way Squarespace functions, I need the filename to be in the title field so it will be displayed when clients are previewing images. I found a work around code for Squarespace that will allow the filename to be displayed below the thumbnail version, but I need the filename in the title field for it to appear when the image is opened up the larger lightbox. Any suggestions are greatly appreciated.

Thanks!
