Hi,
In Blender 4.0 is finnaly possible make for example forest where every tree different shape? First make tree generator group and connect as instance on points? I hope you undarstand what I mean 
Why souldn’t this be possible already ??
Well instances are… copies of the original… that’s the definition of instance… you may just use a Realize Instances node and use for example the location as some seed to some random parameters ??
