Is it possible to return the Layer Name after I preform a Merge Visable action?

I've learned that Photoshops action system is not the most robust and I find I'm scripting more than anything but I am looking for a way to return the layer name after calling evenetMergeVisible:

    error = sPSActionControl->Play(&result, eventMergeVisible, desc, plugInDialogSilent);

    if (error) goto returnError;

I don't know how I can use sPSActionDescriptor->GetName() to return a uninitialized PIActionDescriptor once I call play on it. There must be a way I can retrieve the created layers name, or even element...
