Sure, but you'll need the source code. Open up the SE.cs file in the AspDotNetStorefrontCore project. Find the MakeObjectLink method. You'll need to add the product type to the RouteValueDictionary
Code:
var dictionary = new RouteValueDictionary();
dictionary.Add(ObjectName + "ID", ObjectID);
dictionary.Add("SEName", tmp);
dictionary.Add("ProductType", "this-is-the-product-type");
You'll have to run a query to get the product type for the current product from the database (just query against the ObjectID variable), then replace "this-is-the-product-type" with the value you get back from that query. Once you've done this, you can use {ProductType} (or {whatever-you've-specified-as-the-first-parameter-for-dictonary.Add}) in the product route in the routes section in the web.config
