Help with a workflow logic

I’m trying to create a workflow that creates deals associated with a company. The full scenario is, I have a deal associated with several companies, those companies are labelled as “Bidders”, they exist in a deal pipeline called “Sales Pipeline”, what I’m trying to achieve is to create several records for the same deal matched with every single company associated to it alone in a different pipeline called “Bidders Pipeline”. So if Deal 1 is associated to Company 1, Company 2 and Company 3, I want to create a workflow that creates Deal 1 – Company 1, Deal 1 – Company 2, Deal 1 – Company 3. The issue I’m facing is that I created the workflow, but it creates only one record  “the deal associated with the most recent company”, I tried changing the avalable records to choose from, to get all the associated companies but it just doesn’t appear. What should I do, given that I don’t know the exact number of companies that could be associated to this deal.
