Open Automator and make a droplet or service that runs `xattr -d com.apple.quarantine` on whatever file you give it. There’s a recursive option for xattr that I can’t remember but I add that one on too; I’ve unzipped stuff that had the flag and somehow ended up with hundreds of files I couldn’t open without GK prompts.

  xattr -cr <file or dir>

Clears all attributes recursively.

Thanks! I'll give that a try.
