How to create a link from the Apple Store which contains the configuration of a MacBook?

I configured a MacBook Pro in the Apple Online Store. Now I want to send the link to this particular configuration, but the link doesn't store the values in it.

How can I share this configuration with somebody?

So:

1. I choose MacBook Pro in the Online Store


2. Choose my model


3. In the options overview, I add RAM and a faster processor


4. I want to share this configuration now, but


5. The link doesn't have the values in it
