Here's another version promoting the extrude seams/edges.

Yeh, I'd normally use this to promote seams/edges but they were looking for inside/outside so prims made more sense. In this example, the promote isn't needed but it may be useful to know for other scenarios.

Hi, you can try two attribute promote sops. 1st after the extrude, 2nd after the bevel. Depending on the topology and what sops you are using, you can often (not always) keep point groups through a chain. I've attached a hip and screenshot.
