Keyframe surface?

can the surface be keyframed (in beta)? in some shots where the car is driving towards the cam then turns and drives away, motor doesnt catch on and loses the car between turns. i feel like if i can keyframe the surface i can show it how it should be tracking. also in beta the manual track versus large movement track doesnt keyframe, in fact those options dont seem to make any difference in how the tracking turns out.

thanks =)
