title: Using JayData mapping with inverseproperty for one-to-many relationships
body: <p>Trying to use the JayData mapping option (per their tutorial):</p>
  
  <pre><code>&lt;script&gt;
      northwind.Products
          .map(function (product) {
              return {
                  ProductID: product.ProductID,
                  ProductName: product.ProductName,
                  CategoryName: product.Category.CategoryName,
                  CompanyName: product.Supplier.CompanyName,
                  ContactName: product.Supplier.ContactName,
  
              }
          })
          .toArray(function (products) {
              console.dir(products[0]);
          });
  &lt;/script&gt;
  </code></pre>
  
  <p>The question is how do I do this in the cases where for example there is more than one ContactName per company, and I want to choose one based on particular criteria (e.g. last updated date). I have already defined the necessary inverseProperties in my model definition (in the js and ts files)</p>
  
  <p>Thanks!</p>
