ProjectLink Activity Change History

Hello,

When working in project link, the container is shared with the supplier that is owner in some activities, allowing him to change duration and/or start date from activities. But when he does that he should inform why the duration/time is being affect. As this reschedule can occur several times, I need to track the changes.

In activity history only information related to dates, like estimated start date and estimated end date are stored in activity history. Is it possible add more attributes to be controled in history?
