Typescript interface factorized key definition

Question

I have some objects returned by an API (namely Dataverse) which contains some keys suffixed with @OData.Community.Display.V1.FormattedValue so I'm starting with this interface definition:

export interface Order {
    mso_name: String,
    "[email protected]": String,
    mso_montanthtcur: Number,
    "[email protected]": String,
    createdon: String,
    "[email protected]": String,
    mso_remisemoyennedec: Number,
    "[email protected]": String,
    mso_marquecode: Number,
    "[email protected]": String,
    statuscode: Number,
    "[email protected]": String,
    _ownerid_value: String,
}

As you can probably guess, I'd like to factorize that a little bit.
I tried to use template literals like:

const SUFFIX = '@OData.Community.Display.V1.FormattedValue'

export interface Order {
// ...
  [`statuscode${SUFFIX}`]: String
  statuscode: Number,
// ...
}

But it's saying

A computed property name in an interface must refer to an expression whose type is a literal type or a 'unique symbol' type.ts(1169)

I don't understand what I saw on the web about it.
Is there a simple way for me to factorize my interface ?

BTW suffixed props are all string values and all props don't have their suffixed equivalent
