@Ryan R yes it is possible to create ports from net names. 1. highlight the nets you want a port to be created for, click that net and press '`k`' the nets will be coloured in red, yellow, green and so on. 2. After highlighting all nets press '`Ctrl-j'`, use the mouse to set the position of the ports. You can later change the port direction if needed, by changing for example '`ipin.sym`' to '`opin.sym`' or '`iopin.sym`'
