Encrypt single note or only encrypt plain text not resource

if notes encrypted,another client sync it ,resource may broken and can't dencrypt,so i want it only encrypt text not resource or can encrypt single note but not all notes

I use Paranoid Text Encryption

Just a cut and paste away from Joplin (or other apps that sync text)

you don't get my idea. i mean it joplin encrypt single note when syncing.
