Enum with custom value

Hi, does anyone know if it's possible to do this in Prisma :

CREATE TYPE "FileType" AS ENUM ('image/jpeg', 'image/png');

CREATE TYPE "FileType" AS ENUM ('image/jpeg', 'image/png');

Because I can't find a way to specify the enum values like this:

enum FileType {
  IMAGE_JPEG = "image/jpeg",
  IMAGE_PNG = "image/png"
}

enum FileType {
  IMAGE_JPEG = "image/jpeg",
  IMAGE_PNG = "image/png"
}
