Updating items through the endpoint /admin/bulk/items changes the created date

Making changes to an item directly at /admin/items with the "edit" pencil icon leaves the "Createddate" untouched and updates the "Modifieddate" correctly.

However, updating existing items with the endpoint /admin/bulk/items gives a result like:
{ignored: 0, took: 8, created: 0, deleted: 0, updated: 35}
and sets both the "Createddate" and "Modifieddate" of the updated items to the actual date, making it a bit misleading and somewhat unusable.

Is there some way to get an update to leave the "Createddate" alone for already existing items? 😁
