You could write an event trigger to record it.

Thanks for your prompt reply Peter.

Sure I could write a trigger to capture and store it, but for such common functionalities seems to me it would be best
tohave it in the engine, vs. each application having to write its own trigger and reinvent the wheel.  

Is there any concerns on adding it as a feature, or is it just backlog? Has a feature request been filed for this?

Thanks,
Patricia
