No, Labels are viewpoint-specific elements so you have to place them in each Viewpoint separately.
I actually did something like this a very long time ago. I scripted the 3D script of my Doors and Windows so a 3D Text would appear in 3D for Doors/Windows when a certain parameter was set to ON. The 3D Text would display the ID of the Door/Window. But that was actual 3D geometry generated as part of the Door/Window 3D geometry.
In AC19 you can select all Door/Windows in a Viewpoint and use the Document\Document Extras\Label Selected Elements menu command to quickly Label them all.
