Как сделать универсальный контроллер для запросов апи с помощью MediatR?

У меня есть контроллер для таблицы с учителями. Если сделать запрос на api/tutors, учителя отправятся в JSON в виде ответа.

Controller

[ApiController]
public sealed class TutorsController : Controller
{
    private readonly IMediator mediator;
    private readonly IMapper mapper;

    public TutorsController(IMediator mediator, IMapper mapper)
    {
        this.mediator = mediator;
        this.mapper = mapper;
    }

    [HttpGet("api/tutors")]
    public async Task<IActionResult> Get([FromQuery] int page = 0, [FromQuery] int size = 30)
    {        
        var getTutorsQuery = new GetTutorsQuery(page, size); // строка с комментарием
        var tutors = await mediator.Send(getTutorsQuery);
        return Ok(mapper.Map<PageDto<TutorDto>>(tutors));
    }
}

GetTutorsQuery

internal sealed class GetTutorsQuery : IRequest<Page<Tutor>>
{
    public GetTutorsQuery(long pageNumber, long pageSize)
    {
        PageNumber = pageNumber;
        PageSize = pageSize;
    }
    
    public long PageSize { get; }
    public long PageNumber { get; }
}

GetStudentsQueryHandler

[UsedImplicitly]
internal sealed class GetStudentsQueryHandler : IRequestHandler<GetTutorsQuery, Page<Tutor>>
{
    private readonly ICrudRepository<Tutor> tutorsRepository;

    public GetStudentsQueryHandler(ICrudRepository<Tutor> tutorsRepository)
    {
        this.tutorsRepository = tutorsRepository;
    }

    public async Task<Page<Tutor>> Handle(GetTutorsQuery request, CancellationToken cancellationToken)
    {
        return await tutorsRepository.Get(request.PageNumber, request.PageSize);
    }
}

Сейчас мне нужно сделать так, чтобы при запросе на api/students и api/lessons также возвращались данные по такому же принципу как у учителей. Можно сделать несколько контроллеров, но тогда будет слишком много повторяющегося кода. Можно ли как-то упростить контроллеры с помощью дженериков?

Пробовал сделать вместо new GetTutorsQuery (Controller, строка с комментарием) сделать new GetQuery<Tutor>. В GetTutorsQuery и GetStudentsQueryHandler заменил все упоминания Tutor на T (ну и в названия классов тоже добавил <T>). Но в таком случае возникает ошибка
