Pothos SDR source settings for below 30MHZ receive on LimeSDR

Hi,

Could someone please post a screenshot of how the SDR source needs to be configured to receive frequencies below 30MHz in Pothos? I know the LO has to be set to 30MHZ and then the NCO does conversion of the signal, but there are no such options as far as I can tell in the SDR source properties. Also, no obvious way how to set this up using python code too.

I think It would be very useful to many people if someone could post an example.
