Just had a response back from Rigol UK...as a few others have said - there's not an updated version the DP832 just doesn't support it. Thanks for the responses all.
...and looks like they've updated their site now as well.

No, the DP832 doesn't have the ability to remote sense voltage.
Only the DP811, DP811A, DP821 and DP821A models has this capability.
Sense and output terminals are present only on the rear of DP811 and DP811A models.
Our website will be updated accordingly, later today.
Many thanks for the feedback and apologies for the confusion.
