Document order when adding to a collection

Hi. In copying multiple items from one collection to another, their order isn’t retained. II don’t see that they are being put in any particular order. It’s not in binder order, or an inverse. It appears random.

Is this something that should be doable?

Thanks.

Yes, this looks like a bug with using Add to Collection or clicking the new collection button to create a new collection out of the selection. It seems to work properly when using drag and drop from one collection to another–create the new empty collection, then switch to the original, select the documents, and drag and drop them onto the tab for the new collection.
