Can I export just PBCS data that has changed over the past 30 mins to csv file

Summary:

Export just PBCS data that has changed over the past 30 mins to csv file

Content (required):

My client has a business requirement to export just data that has changed over the past 30 mins to csv file. Using groovy doesn't seem to be enough since data changes could be triggered by editing cells in a form, but also by a business rule, data load, etc. Is there a way to identify the blocks that were modified over a period of time to export just those? Maybe something that leverages Essbase Intelligent Calculation?
