Import Skeleton Unreal 5.6 and 5.7

Hello,

I created a lever animation in Blender consisting of two parts (the base and the lever).
When I import it into Unreal 5.6, there is only one skeleton—which is exactly what I want—but in Unreal 5.7, it splits the skeleton into two: the base and the lever.
Is it possible to combine the two into one? There is a “combine” option, but it applies to static meshes.
Thanks.
