Maybe https://grass.osgeo.org/grass77/manuals/t.rast.to.rast3.html can be useful here?

Are there any ideas how to run this process in batch mode for example?

I would like to combine potentially 100s of 2d rasters into one 3d raster.

Instead of using r.to.rast3 which could take a long time to prepare the setting, is there a way to export the raster as point files, and combine them using for example MsAccess, and then reimporting them into one 3d raster file?

Alternatively, is it possible to combine several 3d raster into one 3d raster?  i could combine ten 2d rasters into one and then combine the multiple 3d rasters into one larger one.
