I think you're talking about a list where you can look up a part number and it will tell you what bag or sub kit it is in. That would be handy, but for me personally, I've never had much problem with going through the parts lists that come with each kit's documentation until I find the part number, see what bag (or sub kit) it's in, and go get it. Common parts like rivets, nutplates, washers, etc. go in labeled drawers.
After reading Johns post above I thought I'd add that as I take parts out of the bag that has multiple parts I mark the parts list with a tick mark to indicate that. That took care of the problem of having to identify similar parts by the parts count in the bag.
But then I also enjoy putting jigsaw puzzles together.
