In the contract structure editor, you can determine which services are pure subcontractor services (third-party services). However, entire sub-projects are often external services. Here, a switch at sub-project level would be important in order to be able to define all underlying services as a sub-contractor service in one fell swoop. The same applies to the subcontractor view. Here, you also want to be able to enter an amount or a percentage by title, which then applies to all underlying benefits.
