How could you use the bRotationFollowsVelocity bool in a projectileMovementComponent but have the yaw used 180 degrees off?

I had to use SetRelativeRotation() to change the yaw of a mesh 180 degrees on an arrow to have it shoot things with the tip instead of the flights. But if I use the bRotationFollowsVelocity bool option to make it fly in a natural arc it negates the effect of my fix. If I saw the code this bool is being used for I could modify it accordingly I just don’t know where to find it as unreal engine is huge and I don’t know where the code using this bool is found.

I have tried modifying the relative rotation again 180 of the new value, the direction of the velocity both positive and negative, I thought I tested every possible combination. What am I missing?
