Add bridge pup on switch to Epiphone Nighthawk Custom Reissue-how?

[rockstar_not]

2013 Epiphone Custom reissue has HSH pups with one volume, one tone pot and coil tap via pull-up on tone knob.

Pup combinations are via 5 position switch of apparently import style as follows
1-bridge
2-bridge+middle
3-middle
4-middle+neck
5-neck

I can't tell where to place a spst on the 5 position import switch to give me tail pup on control so that in position 5 I can get neck+bridge.

I have photos of the control cavity

You can't get what you want with the standard 5 position switch. You'll need a super strat switch.
