Keep existing easing when separating dimensions

Hi currently when you sepperate dimentions in Ae it deletes the easings.

Please reapply the easing. 

I get that it's not possibe to do when you go from 2 different easings back into 1 property.

But when you go from 1 property to 2 properties this should be possible. (just apply the same easing to both keyframes)

Or from 2 properties with the same easing to 1 property it should work. (just apply the same easing to the keyframe)

Much love,
