Hi! Thank you for your feature suggestion. Yes you are right, it is currently missing the option to load presets especially for animation related properties. Adding this would be essential for saving a lot of time.
One thing which need to think about is how to make these presets adaptable, since changes like position or scale can depend on the size of the object the effect is applied to. But with good import/export system I think we can make the presets flexible enough to adjust it.
Thank you again for your feedback, I'll definitively add this feature in the roadmap.
