Image Upload - Filter files being uploaded by Filelist

Need a plugin or method to help with this use case. Will have a folder of 100’s of images and a CSV with certain filenames. Need a way to have Bubble reference the filenames and only upload the images who’s filename is in the list.

I can handle parsing the CSV to get the list of filenames. What I need though is a way to filter the files to be uploaded PREUPLOAD. I know I could probably get this to work by uploading all and then deleting, but would be so much better if I could just block the upload of any images not included in the list.

Any ideas?
