That is at least a starting point.

Aha, the :num part is pin number or -label.
Ok, found it in $gitroot/gaf/docs/wiki/geda-na_howto.html

Ok, the first step would be to made is:
. take such a net-symbol
. attach a short net line to it
. connect it to the pin
. grab the pins pinlabel and
. set the net-symbols net attribute to the pinlabels value
Then I could manually copy that net-symbol+net-line to the next
place/component.
Can a plugin do such things?

Why do people use auto-routers...
