Using the tween function for specific points?

Hi, this question was last asked by another user 7 years ago: https://forums.toonboom.com/toon-boom-studio/general-discussion/using-the-tween-function-for-specific-points

Has anything changed since then? Is this something that I can do now? Basically the question is whether you can add motion tween to contour points, much like in Anime Studio Pro.
