When in transformation editor, enable the ability to right click on an invalid function and create it

When users are creating views (tables exists), they cut-n-paste a query in. But it contains database specific procedures/functions. It would a nice feature to enable the right click on the invalid procedure and allow it to be created, because the metadata is there to define the parameters. The only unknown is the result, but opening the function editor at this time could allow for setting that.
