ADC12DJ5200-SP: The GUI only has JMODEs 0, 10, 21, 30. How to use JMODE31 with the GUI?

Part Number: ADC12DJ5200-SP

Tool/software:

Hi team,

My customer has been using JMODE30 which has 12-bit, single channel, DDC bypass, 8 lanes 8b/10b. They would like to use JMODE 31, however the GUI only has JMODEs 0,10,21,30 for their ADC so I they are not able to select other ones. Is there a way to get a custom configuration so that they can use JMODE31 with the GUI? 

Thanks,
Lauren
