Thanks. Bit of feedback though: just want to say it did work better when
you had the drop-down menu and added it that way. Simple. Not this
work-around which takes slightly longer.
I did do that, (add item to the master Watch List, then open the master
Watchlist to move the item to one of your separate lists). But noticed
when I removed it from master watchlist, it gets removed from custom
watch list as well.
