Optimizing Auto-Update for Email Lookup on No Results Returned

hey Clay team! I've got a question around filtering when there are no results. So when I filter out my client's Do Not Contact list, I use "Lookup single row in other table" with their DNC list. Once I get back "No Record Found", aka the lookup returns no results, then I want to start spending credits to get their email data. But not before. Is there any way I can make this auto-update as soon as "No Record Found" is returned? Right now, the only conditional I can use on the email data column is !{{Lookup Single Row in Other Table}} and this conditional is if the column has returned the result "No Record Found" OR if that lookup never ran / is queued. So if I run this column before the Lookup column is finished, I would spend email credits on ALL rows where the current result is "Queued" or "Missing Input" or "Error" because these are no results aka !{{Lookup Single Row in Other Table}}. This isn't what I need. I only need email credits once I know the lookup has come back negative / no results found. Right now, I have to babysit this 6k+ column as it loads BEFORE I can start looking up email addresses. This one ability would save me seriously like 5+ hours/wk. I recorded this short loom for context, but the above is the TLDW: https://www.loom.com/share/77d3ed3db1594a89a835ece0b8a84ccd?sid=7fe4c86a-9b00-4056-8aac-fddf1b677222
