You may be remembering the drag and drop opportunity wall that we've shown a time or two. Unfortunately the drag and drop interactions there move items from queue to queue, rather than reordering them.
I can only think of one very hack way of getting this done. Add the following set of actions to the queue "Item on-click action sequence." 1. Update a field value (pinned_c = true). 2. requery the model, If you have the model default model order on pinned_c this should move the selected items to the top.
