Filtering Date Changes from Message Scenario 'Activity Moved' event

Hi Team,

We need to display an indicator on an Activity if it is rescheduled to a different date. We considered using the 'Activity Move' event in the message scenario to set a flag with 'Set Property'. However, since this event is also triggered by resource changes, we are encountering challenges.

Is there a way to differentiate between resource changes and date changes within the message scenario using blocking conditions or other methods? Alternatively, are there any workarounds to achieve this functionality solely within OFS, without involving external middleware systems?

Any insights would be greatly appreciated.

Thank you.
