How to use the NCOs in the ADRV9009

I am very interested in how to use the Tx and Rx NCOs in the ADRV9009.  A couple of questions:

1.  Am I correct that this is a new feature (not available in AD9371 or AD936x)?  

2.  I did find the taliseRx(Tx)NcoShifter api commands, for us with the "IF conversion stage."  But is there a way I can access these with TES?  I see a grayed out box "RxDdcResponse" that seems like it has the right functions.  But it is always grayed out.
