When I merge duplicate records (specifically belonging to children) their attendance timeline isn't carried over from when they've been checked in and marked as “attended” to a class/event. This is a huge issue for us as it is very important to see when a Visitor last attended a class, for example.

I'm assuming and nearly positive this does not happen with Gifts, meaning the merge transfers that info over to the correct record, so why does it not happen with attendance?
