At the moment there is no plan to do so but we will add that to the wish list.
For now you could write a simpleTRiLOGI program that execute a series of "Save_EEP$" to save the menu strings to the EEPROM space. You can ask your customer to first upload this "Menu creation" program to the PLC and let it run once. It will be helpful to have an LED or LCD display to indicate that all the EEP$ have been saved and then the customer can next upload the actual program to the PLC. Both files can be uploaded using the TL5Uploader program.
