Unfortunantly it's about halfway between a Pronto and a Pronto NG. For the original Prontos, there was no grouping but you could copy multiple buttons into a panel (kind of like a button but had no actions) and then move the panel with the buttons contained.

With the Pronto NG there's full grouping and multi-selection editing, so you can select multiple buttons and move them as an entity.

Alas the Neo has neither. You could try using the grid and snap-to-grid setting to at least make it easier to line them up (and don't forget the cursor keys for fine movements).
