c# - Can I pass complex object in additionalParameter of uploader?

Question

In my angular code I'm passing form to API. I use Ng2FileUploader. During setting options I added additionalParameter:

addSubject() {
 if (this.subjectCreationForm.valid) {
  this.uploader.setOptions({url: this.baseUrl + 'Subject/AddNewSubject', additionalParameter: {
    userId: this.authService.decodedToken.nameid,
    subject: {name: "test", description: "test"}
 }})
  this.uploader.uploadAllFiles(null);
 }
}

In my API (C#, .NET Core 3.1) I can get userId, but subject is not recognized.

This is SubjectDto in API:

public class SubjectDto
{
    public int Id { get; set; }
    public int Price { get; set; }
    public string Name { get; set; }
    public string Description { get; set; }
}

And controller:

    [HttpPost]
    [Route("AddNewSubject")]
    public async Task<IActionResult> AddNewSubject([FromForm]AddNewSubjectCommand command)
    {
        if (command.UserId != User.FindFirst(ClaimTypes.NameIdentifier).Value)
            return Unauthorized();

        return Ok(await CommandAsync(command));
    }

Command model:

public class AddNewSubjectCommand : IRequest<Unit>
{
    public string UserId { get; set; }
    public SubjectDto Subject { get; set; }
    public ICollection<IFormFile> Files { get; set; }
}

Result now:

Is it possible to pass complex object like subject and map it to SubjectDto when passing FromForm?
