Export and import multiple Integrator projects in one step Merged

We have split our ETL processes into several different Integrator projects to keep everything modular and maintainable. However the deployment of a new complete release from a development to a production system is quite annoying: We have to export every single project separately. And on the production sides it is the same: We have to import every single project separately. It would be great to be able to do this in one step. Thanks :)
