Yes, there is a smarter way to do so with Data Services Workbench, introduced in DS4.1.
Inside DS Workbench, it has a quick replication wizard that with only 6 simple steps allows you to quickly and painlessly replicate large amount of tables from source to target systems without the need to manually create dataflows individually. You can execute your project directly in Workbench, unless there's need to further enhance (which doesn't sound like your use case) you can import to Designer to enrich your ETL logic
DS Workbench is part of DS4.1 installation.
