Ability to have multiple drafts in Migration

Was working with a customer who mentioned the following idea -- It would be great to have the ability to have multiple drafts in migration -- Currently, the migration package does not have the ability to have multiple drafts in it to migrate functionality to production. This is problematic for our team. Our use case is that our team has multiple developers so it would be helpful to have multiple drafts so each developer can put together their own migration package to ensure smooth delivery. The volume of stories we deliver does not make it feasible for all developers to add into one migration package as it makes it very complicated to deal with any failures.
