Adding events to specific objects

Is it possible to add an event handlers to a specific object, or can I only add the event to the document then when something changes check if the object that raised it is the one I want? The documentation seems to indicate that no I have to check if the object is what I want…

You need to subscribe to the Rhino event(s) that handles Objects being added/ modified
This one particularly I wanted to point out, since a lot of events happen when editing an object:

then in the event handler, raise a flag and in an Idle event handler, handle the stuff you want, based on the raised flag.
