Quote line item description from producttemplate change

Question

Hi, 
 for a customer we have a requirement that based on a dropdown field in the quote we retrieve a specific product template description field. We have a description field per language. So in this case when we have the quote set to 'Fr' and we select product A it should use the value of description_fra from the product template in the quote line iten. If we create a quote with language set to 'EN' it should read description_en etc. 
 In the past I copied the modules/Quotes/clients/base/layouts/quote-data-list-groups/QuoteDataListGroupsLayout.js to the custom directory and made a change in there that would do this. Since in sugar 11 a change was made in this file this causes issues. I tried to extend the original file like 
 ({ 
 extendsFrom: 'QuoteDataListGroupsLayout', 
 initialise: function(options){ 
 this._super('initialise',[options]) 
 console.log('custom initialise function') 
 }, 
 }) 
 but this results in a non functional quote line item functionality. Did someone already look in how to extend that functionality in the past?

We implemented exactly that request for a couple of customers. 
 
 Step 1: Create same dropdown field in QLI; 
 Step 2: Copy that dropdown field from Quotes to QLI via QuoteDataGroupListView.onAddNewItemToGroup for new QLIs and QuoteDataGroupLayout.bindDataChange for existing QLIs. 
 Step 3: Create a sugarLogic formula in the target description field in QLI GRID which fetch appropriate field from Template based on sync dropdown field.
