Mapping the weapon interval knob?

[Sprool]

I'm trying to map as many of the cockpit controls as possible to my button box with rotary controllers, but I cant find anything for the weapon interval knob, the VA, RAKT, HO, 10m - 60m options. For using the rotary controllers I need an up/down option just as there are for the weapons selector knob and master mode selector. 

Does anyone know if thee are keybindings possible for weapon interval select up/down?

I'm pretty sure that it used to have up/down commands - but it seems they have now been replaced with direct commands for each settings. While I prefer it this way - best option would have both choices available.
