Optimizing AI Content Creation for Targeted Outreach Campaigns

Hey Clay community! 👋 I'm building an outreach sequence where step 2 includes AI-generated campaign ideas, but it's only sent to leads who don't reply to step 1 after 2 days. Is there a way to set up conditional AI enrichment so the AI content is only created for leads that actually reach step 2? Or should I just generate the AI variable for everyone upfront? Mainly asking to save credits and keep the workflow clean - no point creating AI content for leads who reply to the first email. Has anyone set up conditional enrichment like this before? Thanks!
