Item revisits can be added from the Site Delivery screen. Their use case is very similar to a One-Off item that you add from Site Delivery, however this will fill out all of the item details for you so you just have to schedule the event.

To add an Item Revisit from Site Delivery

1. Use the search filters on the Site Delivery screen to find the site you want to add a one-off for.
2. On the Placement Items tab, select the item that you want to add a revisit for, then right-click and select Add Revisit.
   Hold Ctrl and click to select multiple items, then right-click and select Add Revisit. This will schedule a revisit for all of the items you selected!
3. The delivery event window will appear with your selected items listed, enter the details and click Save.
4. The screen will now refresh and the item that you added will now appear in the Delivery Events tab for the site.
