Automatic centerline generation and post processing steps

Hi all,
I have a stl file for a bifurcation case (along the Z axis). I want to generate the centerline for this geometry.
In the next step, I want to create the boundary planes perpendicular to this centerline (on the user-defined z coordinates)
and in the last step, I want to extrude the geometry in the direction of the centerline vector on these slices (adding the flow extensions) with the user-defined value in z direction

Is this doable in 3D Slicer?
Could you please help with the required steps?

Thank you.
