Is it possible to remap save/load states keys?

[Jayinem]

Either remap keyboard or set keys for them to a controller? I saw nothing in input > hotkeys I was a little surprised. I can just use joytokey right now but I was hoping to have all of my save states as F1 and my load states as F3 because I have that set to a certain button combination but MelonDS has load states as F1 so just any other key possibility would be better for me.
