Can i use -force-d3d11 option when launching from UE4 editor?

i find that if I package my game and launch the exe with the -force-d3d11 command line option i get my desired 75FPS.
when i launch it from the UE4 editor the FPS is horrible (like 40).
is there a way to modify the launcher in the editor to use the -force-d3d11 option ?
