Shortening querystring names from view model

I am looking for a way in my view models to shorten property names in the querystring for a search form. For example, the verbose property name could be query but you see q in the querystring.

Currently, I am doing the following to achieve this.

public string Query { get; set; }
public string q
{
  get
  {
    return Query;
  }
  set
  {
    Query = value;
  }
}

I would think it might be easier if there was a data annotation to help with this.

[Querystring(Name="q")]
public string Query { get; set; }

Is there a better way to do this that I am not thinking of or is it possible to code my own data annotation like that?
