Could you all please add functionality into ArcMap/ Pro to export features from a layer into an existing feature class. Currently the Data\Export Data, Export Features, Export Table options output a new item. In the world of enterprise GIS and fixed data schemas it would be extremely helpful to be able to set a definition query or make a complex attribute/ spatial selection then export those features into your existing data structure with the help of a simple data loader.
So the workflow would be: setup local data, create a layer, make your selection/ query, Data/Export Features, select feature class to output to, map fields in simple data loader....job done. Get another cup of coffee.
Thanks for your consideration.
