The biggest issue with the Original/Latest Source drill-down 1 & 2 is that they’re not editable (read only) but are reset when the Original/Latest Source is modified (which makes sense in certain use cases). However, if you modify (by mistake or not) the Original/Latest Source you lose the data in the drill-downs and even though these remain in the property history, you cannot restore them anymore… Is there a way to modify these via API maybe?
