Set family name by list

Good morning, everyone!
After creating many “solid by loft”, I assigned a name to each one by using the “+” command that joins the x variable to the y variable. The x is important because it recognizes and counts the solids I created.

However now I’d like to change this process, I want to give each solid a different name, taken from my excel list.
Does anyone know how to help me?

Thanks! JC

Maybe this would help:
