There is no command to open a scroll by its name. You can only access scrolls via buttons, using select_ui_element button_name and simulate_mouse_click commands. As far as I can tell, there are no addressable UI elements for the individual building cards in the hud_show_buildings_tab. If you try to right-click on hud_show_buildings_tab itself, you get the settlement list scroll instead.
What you can do, though, is tell the user to look at the description with something like...
Code:
monitor_event SettlementTurnStart SettlementIsLocal
and SettlementBuildingExists = building1_from_edb ; or SettlementBuildingFinished
and I_ThreadCount building1_Thead = 0
e_select_settlement
point_at_card building building1_from_edb
advance_advice_thread building1_Thead
end_monitor
