In many cases I need zonal polygon stats for different images than the one used by the LMSS process (e.g., used PCA for the segmentation but then need the stats of the original band values). In these cases, I just repeat LMSVectorization with the same segmentation raster, but with the image I want the stats from. Now, this takes time and learn from Michel JUlien that "most of the time spent in this step is about building a segment map". Could it be possible having an equivalent application that would not actually make the vector but just the table? (sort of zonal ComputeImagesStatistics). I understand this would be a lot faster. I know I can use ConcatenateImages (should it not be called stack?) or make a vrt file and apply LMSVectorixation only once, but it is often the case that you think on additional layers later on...
