Hi,
Starting with Workflow Manager 10.0 SP2 (I think), the sample steps provided with the desktop software include a step called "ExecuteGPTool", which is similar to the "LaunchGPTool" custom step. Have a look in the Workflow Manager install directory under "...\Developer Kit\Samples\CustomSteps\ExecuteGPTool".
Also, keep in mind that the "LaunchGPTool" step can run geoprocessing models and scripts. It sounds like you may just need a model that copies some features from one location to another...?
I hope that helps.
