Assembly count

I’m trying to count the amount of assembly instances in my project. So let’s say I have assembly A which occurs 2 times, B three times and C one time. I would like to get them in a structured list
A
A_instance 1
A_instance 2
B
B_instance 1
B_instance 2
B_instance 3
C
C_instance 1

When I use ‘AssemblyType-All Elements of Type’ I obviously get the types but not the instances.
When I use ‘AssemblyInstances-All Elements of Type’ I get a flattened list of all instances.

Could somebody help me get this list structured? The Clockwork package has some Assembly-specific tools but not the ones needed for this.
Thanks in advance!

Ah found it! Using two Clockwork nodes I found a way around:
