Optimizing Claygent to Scrape and Score Unique Company Contacts

Hey everyone, i have a list of 20k contacts. many contacts are the same company. I want to use claygent to scrape the company website and determine if they are a good fit for our company and score them. i obviously dont want to burn credits for the same company if i already ran that value. Not having any luck with run conditions, i was thinking "do not run if value in /website is not unique" but no luck. Suggestions?
