Snap view plus button combo

[Sledgearoo]

In the old version of IL-2 I had my snap views on my the stick's hat but I also had a button which also added a 'Look up'. So, for example, if I snapped left and pressed that button I'd look out over my left wing and also up from that view at the same time. Maybe I'm missing something somewhere but AFAIK this doesn't seem to be doable with BOS. I'd like to map this combo between my stick and a button my throttle (I have a T1600M). IIRC in the old version of IL-2 this command was called '+look up', but I might be wrong on that point.
