Is there any way to add error code to ModelState error

[mo-esmp]

I'm looking for a way to add error code alongside the error message to ModelState.
for example

ModelState.AddModelError("ErrorKey", new { Code = 4001, Message = "Some error message" });

For some bad requests client should do an action and comparing error message is not an ideal solution for making a decision. ModelState.AddModelError method only accepts two parameters, an error key and a message. Is there a way to achieve this or something similar?
