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. 

Its just a quick idea… and probably stinks.
