Vary instance attributes per point (for-each node)

Say you wanted to scatter a bunch of random shapes. For example, using "Instance on Points" on a cylinder to get this result:

Ideally, the setup would be simple:

Instead, it takes far more nodes and only works for a small number of shapes (credit roxya):

Now imagine you wanted 100 different shapes. This would be extremely difficult and time consuming.

Houdini has a "for-each" node to deal with this problem: sidefx.com/docs/houdini/copy/tutorial_stamping.html

This allows as many shapes as you wish:

It would be really good if Blender had something similar.
