I see in Windows 7 that when you do not have the Always show all icons and notifications on the taskbar option enabled (see below), the setting for individual applications is to Only show notifications.

Is there a magical way of changing the default to Show icon and notifications (see below) instead of Only show notifications?

I.e. when a new application comes along and adds an icon to the system tray, it defaults to showing the icon and notifications. I like the majority of the icons down there as they offer quick access to whatever programs are running BUT I still want to selectively hide the few that I do not want to see down there.
If I enable Always show all icons and notifications on the taskbar I can't hide any. If I disable it, I have to go through every single application in the list and change the option, then keep my eye on it for any new applications. Hence my question.
