Show custom Attribute with SCP for Configurable Product Magento - magento

Question

I want to add values from Custom Attribute to short description of Configurable Product in Magento. I am using SCP module to show dynamically short description, title and price for this one regarding to "Associated Simple Products ". The price, Title and short description work fine but it not change the long description and not show the custom Attributes associated to Simple product.
Can some body help me with this problem? I need some indication how can I do that?
I think that I can do it on the original file configurable.php from SCP (Simple Configurable products) module that I attached to this post but I am not sure.
Thank you in advance.
