Using Automation to add a certain label to all cards in a certain list (list and cards exist)

[Rudy Scala]

Hi everyone,

I have created a number of lists with cards in each list. I would like to add a specific label for all cards in a unique list. The list and cards have already been created. is there a way to create a rule or action that tells Butler - Add [Name] Label to all cards in [Name] List?

Thanks!
