Constant AOA SAS mode

[Jonfliesgoats]

Since there is no wind or turbulence to speak of in game, could we get a SAS mode that holds a constant AOA?  I imagine this would be easy since alpha will always be the difference between the longitudinal axis of the craft.  You could set a craft delivering a heavy payload to hold an efficient AOA without constantly compensating for the curvature of Kerbin.  This would also be handy for space plane reentry.
