ConnectPort-LTS8-MEI; How are the serial port descriptions set such that they are visible in the portaccessmenu?

Cannot find any means for setting a port description for each port. Looking at the config (backup print) I only find a description field for each port in the autoconnect config section, which does not appear in the portaccessmenu.

The latest firmware (1.4.5) even mentions adding the ability to use Capital letters within the serial port description.
