I=92ve done that, except for the dotted line. When I use this method, = the pins are scattered about the schematics, close to the circuits they = connect to. This saves a great tangle of nets. The other way, my favorite these days for big connectors, is to use = pins2gsch = (http://www.gedasymbols.org/user/john_doty/tools/pins2gsch.html) to = control the connections. The connector symbol itself is just a box with = no pins (but I draw a bus to it). The nets are named connections to the = bus, pin numbers are tabulated. The tables go into the LaTeX docs, = easier to read and reducing clutter in the schematics. Weirdly, some advocates of database-driven netlisting don=92t seem to = like this approach. But since the implementation is entirely in add-on = scripts, it is completely a matter of user choice. I also would hold this up as an example of what one can do with = well-factored software controlled to the user. Pins2gsch depends on the = fact that gschem and gnetlist are separate, and that each models the = information fundamental to its job, but not much else. If gnetlist was = designed to prevent the user from doing crazy things, this probably = wouldn=92t work. No developer imagined this as a feature, but the = possibility was implicit in clean design.
