I have created a layout with two watchlists. The first contains the Morningstar Industries. The second contains the subindustries and stocks from the active industry in the first watchlist. I did this by building a block diagram for the second watch list.

Is it possible to develop a block diagram for the second watchlist that will select only the subindustries (without the stocks) from the active industry in the first watchlist. I cannot figure out how to do this.

Thanks,
