Simple enough to do.
When in game, change the keybinds for your primary hotbar so that they're like this:
123
456
789
0-=
to (all on the numpad)
/*-
789
456
123
IE, 1 would become numpad /.
Then you can have binds for both 1 to = on the top of the main keyboard and also the layout you like on then numpad.
