instruct ef core to inject some runtime value when constructing entity

[mhDuke]

I must shout out to ef core team, and arthur. you guys doing splendid job.
I am experimenting to implement internationalization with the help of ef core. currently each entity has a List of another object which holds the translatable properties. example code

public class Language
{
    public int Id { get; set; }
    public int Name { get; set; }
}
public class Employe
{
    private readonly Language _language;
    public Employe(string name, double salary, Language language)
    {
        Translations = new List<EmployeTranslation>();
        Salary = salary;
        UpdateName(name, language);
    }
    private Employe(Language language)
    {
        _language = language;
    }

    public int Id { get; set; }
    public double Salary { get; set; }
    public string Name => Translations.FirstOrDefault(e => e.Language.Equals(_language))?.Name;
    public ICollection<EmployeTranslation> Translations { get; set; }

    public void UpdateName(string newName, Language language)
    {
        var existingLanguageTranslation = Translations.FirstOrDefault(e => e.Language.Equals(language));
        if (!(existingLanguageTranslation is null))
            Translations.Remove(existingLanguageTranslation);

        Translations.Add(new EmployeTranslation(language, newName));
    }
}
public class EmployeTranslation
{
    public EmployeTranslation(Language language, string name)
    {
        Language = language;
        Name = name;
    }
    public Language Language { get; set; }
    public string Name { get; set; }
}

I would like ef core to inject a runtime Language object or even an int LanguageId when constructing several entity types via the private constructor. in Entity types with constructors documentation it clearly says

Currently, only services known by EF Core can be injected. Support for injecting application services is being considered for a future release.

but that was 3 years ago. is it possible for ef core 3.1? or even ef core 5?

currently im using a global filter on Translation entities to filter for a current request language as a workaround. or perhaps as long lasting solution.
