I guess that like the Boxster they use a container that connects to the header tank in place of the cap and can be pressurised by an external vac pump,

This is from the Porsche BoxsterS Tech training guide....

The filling device 9696, bleeding adapter 9696/1 and vacuum pump VAS 6096/2 are
required for proper bleeding. All shut-off valves of the thermal management system must
be open during the bleeding procedure. This takes place via a corresponding guided
procedure defined in the PIWIS Tester
