Bogus Mocking Data Same Values For 2 different properties

Question

Bogus Mocking Data Same Values For 2 different properties is it possible to have 2 properties have same value in the fluent api.

var users = new Faker<User>()
   .StrictMode(false)
   .RuleFor(o => o.Id, f => orderIds++)
   .RuleFor(o => o.UserName, f => f.Person.FullName) // This needs to be same as the next property
   .RuleFor(o => o.NormalizedUserName, f => f.Person.FullName) // This should be same but uppercase

Wanted generated data:

[
  {
   userName: "Ivan Horvat",
   normalizedUserName: "IVAN HORVAT"
  },
  {
   userName: "John Doe",
   normalizedUserName: "JOHN DOE"
  }
]

I want each of the entities generated to have same UserName and NormalizedUsername but each entity its own.

You can also have two properties with the same value by using the RuleFor(Prop, (f, usr) =>) overload too.

void Main()
{
   int orderIds = 0;
   var users = new Faker<User>()
      .StrictMode(false)
      .RuleFor(o => o.Id, f => orderIds++)
      .RuleFor(o => o.UserName, f => f.Person.FullName) // This needs to be same as the next property
      .RuleFor(o => o.NormalizedUserName, (f, usr) => usr.UserName.ToUpper()); // This should be same but uppercase

   users.Generate(3).Dump();
}

public class User{
   public int Id{get;set;}
   public string UserName{get;set;}
   public string NormalizedUserName {get;set;}
}
