If a large number of connection points are to be classified in the same way, it makes sense to use a prefix or regular expression. In this way, you only have to classify the specified number of points once. To do this, use the context menu command Select connection points via formula [Choose connection points via formula].

You can find an example of this at Section 5.12.11.29.1.2.1, “Classify a number of connection points in the same way”.
