It is not that hard to assign pins in the editor. Right click on the part and open in the parts editor. Go the connections tab and set the total number of pins. Then go to each view and click on the unassinged pins in the connector list and click select graphic and then select the pin on the graphic. Do that for all the pins that do not have check marks already. Once you are done you should go into the meta tab and make any changes you feel are needed as well as assign the pin names in the connections tab and then save the new part ( I have not tested it an do not know if it has any issues ).
Also are you aware that is not just an esp32 module but rather a breakout board from a specific company for a esp32 module. There is an esp32 module available by itself.
