Change flying key A / B settings in the background?

Preparing shows, especially with greenscreen / chroma keys, having two keyframes for flying keys often isn't enough for me.
Is there a way to load a setting for keyframes A or B in the background, without changing the actual live flying key setting?
So I can then use the Run to A or B to change the position smoothly.
I'm up to coding macro XML if necessary, but not sure whether that's the solution or where the keyframe settings are stored.
I'm mainly working on a Constellation 8K, also running bitfocus companion and mixeffect.
cheers,
Andi
