I am not sure I understand exactly which views you are trying to create, but here is what I do and maybe you can apply it to your situation.
All hat functions are programmed for standard views (ie. forward right, right, back right, back, back left, left, forward left) except UP which I have set to forward-up. I have programmed button 2 on my joystick to view UP. This acts as a modifier to my hat views when using both at the same time. So, if I use my hat to view "forward right" and simultaneously press button 2, I get "forward right up".
Hope this helps.
