Dynamo family name elements node?

[ShineThrone]

Dynamo has "parking elements all" node,

But no "family name elements "node? 

Because I have parking 5 type in family name A, other family name B, 

I want to do two parking number; A type 1~N, B type 1~N.

Is this a question or an idea? Either way, you'll have more luck at the Dynamo forum.
