Hi, I have to manage this situation: we develop a product that have several components (e.g. Server, Client and Mobile). Sometimes a customer ask to develop for him some new features, so we'd like to create something similar to a sub-project in which are available all the features of the product project (components, versions,...). At the same time, from the product project all the issues created for the customer sub-project should be visible.

Is there a way to handle this situation? Or I can use only custom fields?
