Boostback Burn in kOS

[Inspierio]

I am looking to do a boostback burn where the engines will cut off when the impact point reaches the space centre. Is it possible to force the kOS script to make the rocket point at a specific angle to burn? I want it to look similar to the image attached.

Why not use mechjeb? I think flyback boosters are possible, though i suhgest using physics range extender though
