How to Filter 404 Errors in Bulk Website Reviews with Clayagent

When I ran Clayagent to review the website, pull description, etc. I am seeing 10% of my results be websites that are returning a 404 message - https://app.clay.com/workspaces/11327/tables/t_3DTvzJKp2hBR/views/gv_DeygWTNvJKud Seeing how to avoid pulling in that data….and if there is no way if there is a way to review websites in bulk to see if they are active/up. Thoughts?
