Cessna 172 battery standby switch spad.next

Thanks. I’m very much a newcomer to this and I think it’s a bit beyond me to program. I did try to assign those commands to the cowl switch of the saitek switch panel, but when I flick the cowl switch, it throws the on-screen battery switch. I think it needs more to get it simulating what happens in the cockpit.
Thanks for your help though.
