[Upload csv] When the file exceeds 100 words, ask for a Favorite word

When the CSV file to upload in GoldenFish exceeds 100 words (for instance, when duplicated a MoonFish segment to GoldenFish using the CSV download/upload feature), it is can be time-consuming, and also intimidating, to choose which words to delete.

Would it be possible to allow the import of files containing more than 100 words to GoldenFish, but ask the user to select a seed words et auto-select the 100 words to keep in the list?
