Target-aligned pixels in re-projection

When experimenting with alternative ways for image re-projection, I encountered the target-aligned-pixels (-tap) feature in gdalwarp. This simple command-line argument forces the bounding-box coordinates of the output image to be a multiple of pixel spacing. This is the same policy as followed in Sentinel-2 products of levels 1C and 2A. How can I obtain this in re-projection in SNAP ? The Mosaic operator seems not to have any handy means for achieving this.
