K2 SmartForms Add New Row based on Enter Key or Arrow Down,etc?

Hi

Is there any possible way on a SmartForm ListView to have "Add a new row" fire off when a user either hits enter to be done with the current row they are adding, or a keydown event or even if they tab and finish tabbing to the end of the row? 

We have a client request where they need to enter a lot of rows of new data, and having to click the add button on the toolbar everytime is cumbersome.

Thanks

Michael
