One click for deleting pictures on Photos

I have had the new Photos 1.0, (2015) for a few months now, and I'm trying to figure out if there is a way that when I click the delete button on my Macbook Pro, the pop-up window stating my decision to delete, doesn't come up. There is no box in the lower left-hand corner of the window, to click "Do Not Ask Me Again", and I'm hoping there is another way to turn that off, so it's just a one click to delete a photo. It's quite nettlesome having to keep pushing enter after delete.
