Condition on basic model to determine if Id of row is in grouping of aggregate model?

Thanks for the response, Bill. I like the idea and it would work perfectly except that I need a way to display only the newest child of each parent. My long-winded post got way too confusing. I only used aggregate fields because you can use them to identify the newest child. I’m unaware of an condition in basic models that will identify “newest”. So, to restate my question, “is there a way to display only the newest child record of each parent in a table?” Thanks for your help!
