How to extrude several polygons on the geosphere?

Question

3D

There is a problem with how extrude behaves on the geosphere:


Depending on whether the polygons on which the extrude operation is performed are adjacent along the edge or not, their common vertex can eventually take a different position. I would like that, regardless of the selected polygons and their adjacency, all their vertices after the extrude operation remain on the same line with the center of the sphere and their copies. How can this be achieved?
