How to add a code modification feature

Hello,

I don't know if it's possible and how to achieve this.... I'm using Catel as MVVM Framework in a WPF application and since I'm using a weaver assembly to convert the auto properties to Catel ones I wish to add as a "task" of resharper the ability to convert this code

public ObservableCollection<string> Fonts
{
get { return GetValue<ObservableCollection<string>>(FontsProperty); }
set { SetValue(FontsProperty, value); }
}
public static readonly PropertyData FontsProperty = RegisterProperty("Fonts", typeof(ObservableCollection<string>), null);


to

public ObservableCollection<string> Fonts { get; set; }

I mean to add it here


Is it possible? How?

Thanks
