Is it possible to contextualize omitted fields via middleware?

This library is amazing. Thank you for your excellent work!

I'm using the new omit features in v0.19.0, and it works great for fields with default values in prisma like createdAt, but I'd like to not expose createdBy and updatedBy in my API:

model Foo {
  ...
  /// @TypeGraphQL.omit(input: ["create", "update"])
  createdBy       User   @relation(name: "CreatedFoo", references: [id], fields: [createdByUserId])
  /// @TypeGraphQL.omit(input: ["create", "update"])
  createdByUserId String
  /// @TypeGraphQL.omit(input: ["create", "update"])
  updatedBy       User   @relation(name: "UpdatedFoo", references: [id], fields: [updatedByUserId])
  /// @TypeGraphQL.omit(input: ["create", "update"])
  updatedByUserId String
  ...
}

I have a middleware that adds a user from cookies to context, and I'd like to use the generated CreateFooResolver, but the mutation fails at the Prisma layer with

Argument createdBy for data.createdBy is missing.

because I'm omitting it from the mutation.

Is it possible to write a decorator middleware to inject the createdBy and updatedBy values from context, or would I need to write a custom CreateFooResolver?
