Transform effect troubles

Hello, im having trouble with the transform effect. When used im not able to add bevels on the keyframes in the timeline and also, the edge rounding is very dodgy and when it does work it wont work with keyframes. im not able to figure out how to make this a preset either?? thank you for any assitance

I've found that I can get better results using the Transform node on the Fusion page. The Spline editor there is much improved over what we get on the Edit page.
