A way to override default example

[HermanPierre]

Hello,
I am currently writing my API swagger doc so for example on this route:

router.GET("/tl/:id", []fizz.OperationOption{
		fizz.ID("get_by_id"),
		fizz.Description("Get by its id."),
		fizz.Response("200",
			"Example of a successful call by id.<br>",
			dedicated.TlResponse{}, nil, GetByIdSuccessExemple),
	}, tonic.Handler(handler.GetById, http.StatusOK))

But if do that I get an error because examples for status 200 are already generated by tonic, so I've added example tags to my response struct:

but some fields of my struct are type interface{} because I can't know the exact type of object I'm getting from my API.
So if I use the example tag on an interface{} type, in my swaggers the example for this field says "string"

But it's not clear for someone who reads this and don't know the project, so I tried using the fizz.Response on another status and I can put some object example values in those interface{} fields...
I could use "default" status code but I think its still not clear in the swagger to have status 200 example with "string" for a field and under it, having an object for the same field :/

Is their a way to override the 200 status/default example ?
Thanks :)
