Quick Songs?

Hi all, just started using Presenter and trying to discover capability. During a worship time occasionally a worship leader will move to a song that is within the database but not on the cue list. With scripture there is an option to use Quick Scripture to add a verse onto the main output screen on the fly. There does not appear to be this function for songs? It looks like you have to work through the process of setting up another cue. Are there any ways around this? What is the quickest was to add a song on the fly for instance if a worship leader just starts with the chorus etc?

Songs will need to be added to the cue list to be presented

Would it be possible to improve this in the future, so even if it was an 'add to cue list and quick launch' button this would make it much easier adding songs on the fly during a service.
