No that’s not possible with cryptomator. And there’s no easy way to find the encrypted files/folders that belong to an unencrypted file. You can search via timestamp, and the community developed a Python script to reveal this. But I recommend to only use this if you feel very comfortable with python and the architecture of cryptomator vaults.
Don’t mess up the structure of your encrypted files/folders. This will lead to data loss. Please do you backups before you play around with encrypted vault files. If you are not 100% sure what you do, don’t touch any of these files
