Hey Paul, thanks for the suggestion. Sadly, this isn't fast enough 1. You can't create multiple shortcuts/copies with references at the same time. 2. You still have to check the boxes and confirm. Also, this is a "native" Windows feature for files, so I would appreciate the same comfort for KeePass entries.
