Advanced PreOrder‑ ALL IN ONE

Customised the app with a bespoke request within 2 hours. Can't ask for more than that. FYI the customisation ensured that items automatically come off pre-order based on the 'end date' that you set. This will ensure we can set hundreds of items to pre-order, safe in the knowledge that when the correct time comes, they will automatically remove themselves from pre-order and continue normal selling with no human intervention required!
