Vigier Guitars

The second position (sinle coil bridge) is to thin for my taste. Is there a way to change the wiring only for that position without affecting the others? Or what other options do i have? I have an indus ,2 humbuckers.
 
Thanks

Have a look here, this is the switch you have and the wiring diagrams for it; https://www.schaller-electronic.com/hp543126/Megaswitch-E.htm
You can always make your own configurations if you change switch.
