independant axis rotation for jit. model

I was wondering if independant axis rotation is possible? Every time I switch axis to rotate around, it resets the previous axis rotation. I was thinking to approach this by somehow saving each axis rotation amount and then adding the current one into the previous one, but not sure where to start, or if it would even work. I've built a small rotation laboratory patch below. I'm hoping to be able to rotate simultaneously on all axis with individual degree control per axis, but even getting one axis at a time but memory for all axis degrees would be ok. I think if one can happen though, so can the other.
