Hi Mads

A suggestion would be to not extend the viewmodel and use extension methods instead - in your example you add a property but really it is a method - a less intrusive implementation would be to make an extension method instead.

public static string GetProductNameShort(this ProductViewModel product)

Which in the template would be 

@Model.GetProductNameShort()

The feature with not returning properties when not included is handled by how we fill the properties of the view model - we have a BulkCreateView method in our ViewEngine that will take a look at the filledproperties settings passed in:

You should be able to do something like this:

var productViewModelType = typeof(CustomProductViewModel);
var propertyFiller = new ViewModelPropertyFiller<CustomProductViewModel>(settings.FilledProperties, productViewModelType);
propertyFiller.Fill(model, nameof(model.ProductNameShort), () => yourLogic());
