physgun & physcannon change slotpos ?

[JoBolos]

Hello,
I am trying to change the slot of the physgun and physcannon on my server I do not like its current position I would have liked to put it with the toolgun namely in slot 6 in bulk that when you press the key 6 you can select them are currently on slot 1 by default.
I looked on the hl2 base files here steamapps\common\GarrysMod\sourceengine\scripts but I do not see any way to change the slot.

If a person is able to change the physgun & physcannon slot it would be really nice of him to share the info, thanks in advance to all those who can help me to see more clearly.
