Spline Components with in child actor Components.

So I have a simple Pipe set-up in UE 5.0.3 that instances Pipe meshes along a spline component and I want to use this setup within another blueprint. However, when I add a child actor component to the new blueprint and select this Pipe actor I can not edit the spline used to create the pipe within this new blueprint. Is this a bug or am I going about this the wrong way? Or is there another way to achieve this?
