FFTB treebank auto update: can I filter out identical items?

Is there a command for me to create a subtreebank of items which are in the dark green category? (Identical between two grammars)? Or a list of the corresponding item ids, is that automatically obtainable?

One way to do this is to use [incr tsdb()], selecting the gold profile by middle clicking, and selecting the new updated profile by (normal) left clicking, and then do Compare–Detail which will bring up a window that shows all of the items that are not identical, so the ones you want will be the complement set. I don’t know an easy way to grab the list of item IDs from this pop-up window, so what I do is hit the PostScript button which produces a :.ps file in the /tmp directory, and then pull out the item identifiers from that .ps file.
