Can you filter a task report to show tasks that have at least one predecessor complete?

The use case: We have desktop publishers that get data from multiple reporting sources. Those sources each have a task, and the desktop publisher task has two predecessors. We currently have our user dashboards filtered on the "Can Start" feature, which works for almost every team except this one.

I doubt there's a way to do this, but there may be a data point I'm not aware of or textmode code that will help filter on this condition in a report: "Show me all tasks where at least one predecessor has completed".

Thanks in advance!
