How to differentiate Default duration and duration send while creating activity.

Hi Team,

We had a requirement where we had to show some indicator in the activity level if an activity is using default duration. The duration is not sent from Source System always and we have not enabled Calculation via statistics. So provided there is no flag sent by source system to indicate whether duration has been sent at creation or not, is there anyway within OFS we can figure out if we are using the default at activity type configuration?

Thanks,
