It would be great if somehow grids could be controlled so that any changes (grid heads on or off, adding elbows) made in a master grid file could be pushed to all links, and any link that needs to make a custom change could override the linked location through either a copy monitor function on a single grid or some other dialog. Currently I have to setup 5 links for each project we do, and by far the most time is spent getting grids propagated to each links views the same as my structural file.
