Managing better the New table and the Existing table options for a Data destination

Hi, I've accomplished some proofs to understand the behaviour of the New table option: if specified then the Dataflow gen2 checks the table existence and so if it is necessary creating the new table unexisting. A such behaviour is good but a little hidden and not immediate to understand; it is good because the Dataflow is created just once time and then is runned more times without changing it. I'd like that the table existence check could be better documented and perhaps the two options could be simplified simply indicating the destination table name. Thanks
