Action on all records?

I see how to define a Custom Action that can optionally be invoked on selected records in the live view. What if I want this to happen without any user involvement other than opening the application or a view?

So, I want to invoke an action on all records when a Creator application is opened, or possibly when a View is opened in the application. A typical action would be checking a date field in each record against today's date - if today is later than the date field in any record, another field in the record would be updated to show a warning.
