How to @override a field from another subgraph using original value from that subgraph

My case is: I have two subgraphs

`products` with type `Product`

```graphql
type Product @key("id") {
id ID!
name: String!
}
```
and `translations` where I am trying to override `name` field

```graphql
type Product @key("id") {
id ID! @external
name: String! @requires("name") @override("products")
}
```

The problem is - I do not know how to tell Gateway/Router that I need a field `name` from `products` subgraph and then I will use it in `translations` subgraph to generate a new value based on original value.

For example: if `name` field from `products` subgraph is `IPhone`, I need to modify it for example like: `IPhone (EN)`.

Is it possible to achieve what I am trying to do ?

The issue names no files, tests, or entry points. Start by reviewing how @requires and @override are handled between the products and translations subgraphs; done means an agreed supported approach or a clearly documented limitation.
