Submenu displaying left on certain item

Hi,

Is this possible to force last item of menu display submenu on the left side ?

If you look at my website, you'll see that the two last items have the submenu going out of screen when on small screen : https://www.screencast.com/t/ooOIa1Qm

As I think a submenu displaying on the right side is best for UX, and have all my menu display left is not a good idea, but it would be nice to be able to force last items to display left when out of screen.

Thanks for your help,
Samuel
