Is it possible to save a custom interpolation/blend for sequencer Curves in unreal engine?

let’s say I set interpolation to user and then change curves between two keyframes in Sequencer Curves, then select the two keyframes and right clicking and save this curve type as a preset, so every time I want something to happen from keyframe 1 to 2, I can select the two keys and select the preset to load onto the two. but does this feature exist? because I couldn’t find such thing
