Creating a Signal for Champion Job Changes in Clay

Hi! New to Clay here, and am trying to create a signal that will detect a Job Change. I know there's the built in "Job Change" signal under the actions dropdown menu on the Clay Table. After reaching out to the support bot, it looks like this signal detects both

I only want the Champion Job Change (Contacts who have their company, and started a new job elsewhere). When talking to the support bot, it mentions using the "initial check setting" in the signal configuration, but I am not seeing that anywhere. I feel like someone must have accomplished this, and I'm just not seeing the setting. For more context - I have 3 tables. 1) All Customer Companies, 2) All primary or ICP related contacts at those companies, 3) Other ICP contacts at those companies that aren't in our CRM. I want to see if these contacts start a new job so that our Sales team can reach out to them with a somewhat warm outreach. Thank you for the help!
