Hi @Hannes_Kerschbaumer, I was totally wrong about propagate! Those adjustments are indeed Properties, and in particular they are Voice column X offsets, which you can propagate.
Those notes position adjustments that you do in the Note Spacing tool, are also visible in the Properties Panel in the Note Spacing section, and you can propagate them to other layouts, selecting the noteheads in Engrave mode.
