Bind a Key to Dash?

Wish we could have a key to dash instead of double tap.  Having to let up off your movement key to loose momentum and dash is self defeating against the idea of dashing.  You have to slow down to dash.  

Would greatly prefer a key that would dash in the direction your mech is MOVING (not facing!)  So if you are running backwards holding down A but facing backwards and shooting you could hit the dash key and you would dash backwards.
