Hi @Blendash ,
The way you describe it, by Scaling each Axis , one at a time, is the best I can think of.
There are other ways, but they are neither faster, nor easier. And let’s be fair 3 Scale operations isn’t really that much work, right?
One of those alternatives, would be, to Select all those end Faces, CTRL+B to Bevel and in the ‘re-do panel’ (F9, or bottom left of the 3D View), enable Clamp Overlap (if it isn’t already). Then M > Merge > By Distance. Select those End Vertices and X > Dissolve Vertices. Chances are, those new Faces don’t end up exactly where you wanted them to in this way.
