VrayMultiSubTex probability and integrated UVWRandomizer/Triplanar

Would be nice we could set a probability per color/map. AKA how likely is a color or map chosen. I'm trying to replace ForestColor and RailClone color with this map for randomization of carpaints, but I wouldn't want to duplicate slots to avoid having too much of a few specific colors.

As per this thread, this functionality would be added: https://forums.chaos.com/forum/v-ray-for-3ds-max-forums/v-ray-for-3ds-max-wishlist/1166803-vraymultisubtex-probability#post1215895 But that's almost 2 years ago.

Also because we're now able to load in multiple bitmaps, it would be nice if there's more functionality concerning the manipulation of said bitmaps, an integrated UVW randomizer or ability to add a UVWrandomizer to all the bitmaps that are batch loaded in the same script would be very helpful. As wel as a Triplanar map.

So we can avoid doing this manually (screenshot).
