Add song to cue list direct from song edit page

Hi, it would be really handy to be able to add a song directly the a cue list from the song edit page. Two examples:
1. You're looking for a song on a certain theme to add to your service, so you start typing key words in the Songs filter. Some possibilities are listed. But you're not sure if they're totally on theme, and hovering over the song only shows a snippet. So you click on the song to see the full lyrics. You find a song you want. But to add it to the cue list you have to go back up to the song menu and drag it from there. But it would be quicker and make sense to be able to add it directly from the song edit page.

2. You've just finished adding a new song to your catalogue. Now you want to add it to the cue list. But you can't directly from the song edit page.

(I've mentioned this before in the comments on a related feature request, but giving it it's own entry!)
