Not that I know of, and I've been using Pro Tools since version 6. I have seen it on some other DAW's but actually don't miss it very much.
There are some easy work-arounds for soloing bunches of tracks; Folder Tracks(place similar stuff into a routing folder and when you solo the folder, you get everything IN the folder). Groups, I always have a group of all my drum tracks, and depending on Group Attributes, you can solo the group by soloing any track in the group. Add VCA's(solo a VCA and you hear every track assigned to that VCA).
Beyond that, I tend to not use solo that much. No matter how good something sounds when solo'd, its meaningless if it sounds bad in a mix
