Targeted Warp Stablizing a Steadicam shot!!!

2 shots in question... first has a bump at the tail end as the cam operator "raises up" and it gets wobbly. Nothing too crazy, but if it wasn't a 40 second shot preceding it, I could see the Warp Stabilizer fixing this in a jiffy at a modest 10% punch in like with any short clip. I dropped the warp on and it resolved the stuff out at the end perfectly, however the top of the shot now sees some odd gyrations of the background, somehow anchored off the talent in center frame, as she's standing in from of a very textured background early on. Suuuuper warpy. Also switch to Position Scalr Rotation instead of Supspace, but still wonky.

Another shot has two moments of jerk very early on, not to a point of motion blur, but too hasty of a move for otherwise a slow and beautiful shot (approx 90 seconhttps://usd.cnv.to/vef/310 ds). I could punch in and conversely motion key-frame the movements against these short bumps to hide the jerks... but like the other shot, if there were a way to target the range of a clip for warp stabilizing, that could work. I suppose I could make an edit after the jerk and then punch-in on the continuation of the shot of the clip following to match the stabilized, then Morph them together if not perfect, but that feels crude. Is there a way to specify a range of stabilizing?

Are there any in-Premiere workarounds coming to mind? I’m getting a dynamiclink error in AE but still troubleshooting around.
