Setting the Custom extent of the Data Frame

Hello,

I am wondering if it is possible to set the custom extent of a map document's data frame using ArcObjects 10.1?

I wish to take an existing map document, modify the custom extent of the data frame and then save it. Much the same way as you would do in ArcMap when editing the data frame properties (see image).

Any help would be appreciated.
