Route Name for HttpGet attribute Name for base generic controller class in asp.net core 2

I have a generic controller, which have several derived controller classes. but I cannot figure out how to handle the HttpGet's since it require constant.

[HttpGet("{id}", Name ="should not hard coded here for derived class")]
 public virtual async Task<IActionResult> Get(int id)

I need the route name because in my HttpPost function I want to return CreatedAtRoute() which require HttpGet's

The route name cannot be hard coded because all the derived class need to have a different route name.

public abstract class BaseController<TEntity, TContext> : Controller where TEntity : BaseOptionType, new() where TContext : DbContext
{
    private readonly IGenericRepository<TEntity, TContext> _repository;
    private readonly ILogger<BaseGenericOptionTypesController<TEntity, TContext>> _logger;
    public BaseController(IGenericRepository<TEntity, TContext> repository, ILogger<BaseController<TEntity, TContext>> logger)
    {
        _repository = repository;
        _logger = logger;
    }

    [ProducesResponseType(StatusCodes.Status200OK)]
    [ProducesResponseType(StatusCodes.Status404NotFound)]
    [HttpGet("{id}", Name = "should not hard code here for derived class")]
    public virtual async Task<IActionResult> Get(int id)
    {
        var optionType = await _repository.FindByIdAsync(id);
        if (optionType == null)
        {
            _logger.LogInformation($"[ID not found]");
            return NotFound();
        }
        return Ok(optionType);
    }
}

[Route("api/v1/DerivedControllerA")]
public class DerivedControllerA : BaseController<TimeOff, HRContext>
{
    public DerivedControllerA(IGenericRepository<TimeOff, HRContext> repository, ILogger<DerivedControllerA> logger)
        : base(repository, logger)
    {

    }
}

Any help would be appreciated, Thank you.
