Hello <x-zendesk-user data-user-name="Matthew Kennedy">365021275188</x-zendesk-user>
As per Joel initial post, the requirement is to carry those system dates across to different fields as they are.
As you noted in your own recommendation, we cannot copy the date last modified across in a bulk load / API call as it will override the date modified. I have reviewed our options with both <x-zendesk-user data-user-name="Sven Roepke">365242248587</x-zendesk-user> and <x-zendesk-user data-user-name="Stephen Linsley">365242270127</x-zendesk-user> and we came to the conclusion we don’t have an elegant way to address the requirements expressed by Future Fund with what is available to us, hence the enhancement request. Thank you for confirming the reference for the enhancement request.
