It woud be amazing to have the ability to configure a Playlist as a master comp playlist. So when browsing through the different playlists you could paste audio on it without having to have it visible.
If you have open all the playlists of a track, you can select a portion of audio of any of them and paste it in the playlist you have visible at the top. But, now since PT 12.7, you can navigate through the different playlists with the shift button + Up/Down arrows, so you do not have visible the comp track but the playlist you are istening. So, It makes sense for me to have the ability to copy audio to a master track, that you should assign first to be the comp Track. This would save hours of work in the life of producers like me when making the comps.
