S2: Programming way to view Master Items on Screen LT

page.master = 0, not export the Master item.
page.master = 1, export the Master item, but not view it on screen.
page.master = 2, for screen, but ignore if bit 1 not set

However, if page.master = 1,  can use LT script "Menu -e 33096" to toggle viewing Master items on screen, but cannot control it.
