There are several FOSS modeling programs with code to make these selections and rip the edgeloops apart as well as make a co-planar surface to once more make the model manifold.

Name one that isn’t a mesh program like Blender or a cad program like FreeCAD. I know of no such program in the slicer realm and there’s a reason as stated above.
