Expedition hatchback

Hi!  I am a dedicated Ford customer.  I have purchased several brand new Ford vehicles over the years and I am very happy with the quality.  I do not trust other brands.  I just purchased my second new Limited Expedition 2 days ago.  I just want to recommend that if the back hatch door is left open, that for safety purposes, the driver should hear a "ding" of some sort once the car starts rolling with the hatch open.  The car Dings for everything else.  It may seem impossible to not know you left the hatch open, but when 3 kids are screaming and you just want to take off, it has happened and things have fallen out.  My 6 year old has pushed the interior button to open the hatch while sitting in the back and I did not know immediately.  Please consider.  Thank you for listening!
