Dynamic write to ArcSDE Geodatabase

I am writing to a ArcSDE Geodatabase with many Features. I want to make sure that only the existing features gets written - for instance:

 

 

MyRoadsPoint

 

MyHousePoint

 

MyParkArea

 

 

So if I create a feature_type called MyParkPoint and try to write this - it will fail because the MyParkPoint does not exist in this database.

 

 

Is there a setting on the writer I have not seen?

 

 

One solution might be to add the existing allowed FeatureTypes - however the allowed FeatureTypes and the Output database will chang between every run.
