AD936x DC Offset

Hi,

I am having problems figuring out how to configure DC offset for my application. The Reference Manual shows that DC tracking is updated under 3 configurable conditions (gain change, SOI threshold, or exiting Rx mode). But for my application, the DC offset should to be measured and applied in 10's of microsecs. Are there options to trigger the DC offset tracking update quickly and on the same rx gain setting? 

Thank you for your help.
