Single axis rotation not possible in sequencer?

Hi, I always seem to come up against this problem in sequencer. Say you want a missile firing toward you, moving around the frame a little- up down left right, but always rotating at the same speed on the y axis (pitch?). Travelling forward but spinning on it’s local y axis. The pivots are correct and the quaternion rotation is checked. Why can’t I just animate the y axis independently ie locally rotate around y? It seems to double transform and wobble all over the place. Very frustrating. Never seen this in any other apps

How would I do this? It seems crazy that it’s so difficult.

In sequencer, on the “Transform” tab under your asset, select the + button (“+ section” when your mouse rolls over it)
Add an Additive Track.
You’ll see another transform track appear below the first. Then animate the Rotation Y axis additively.

Using an additive track on the y axis seems to work. A bit weird that this is necessary, but so far it’s a workaround that is doing the job.

actually not sure that solved the problem entirely. it helps. would be really nice to just have the option to rotate each axis independently.
