Downloads - date sort order, how?

[Beepeeaitch]

We have a downloads category for PDFs of a club magazine. At present the order downloads appear in is based on most recent. Ordering by name is no good. I need to be able to order by a data field somehow. I've tried adding an 'Extra Field' of type 'date' but it's not selectable in the order-by list. Any ideas please?

The only items you can order by at present are the items shown in the "Default sort order" list. There is no way in which to order by a custom field at present. As you are still asking if someone else may have other ideas, I have moved this to the community support forum. If you would like to see sort orders for custom fields added, please feel free to post this as a suggestion within our feature suggestions forum.

Thanks for the reply @Marc Stridgen, I've not found a workaround yet. One of the sortable fields is 'Start Date'. Do you have any idea what this relates to and where/how I would set a Start Date for an item?
