removeMultiInstance is undoable, NOT queryable, and NOT editable.Removes a particular instance of a multiElement. This is only useful for input attributes since outputs will get regenerated the next time the node gets executed. This command will remove the instance and optionally break all incoming and outgoing connections to that instance. If the connections are not broken (with the -b true) flag, then the command will fail if connections exist.
|boolean||(true if the instance was removed, false if something went wrong, like the attribute is connected but -b true was not specified)|
