No worries @Steven_Hansen,
I checked in the Revit 2017 API and i still can’t see a way to modify the location. I know a feature request has been submitted for this, but I suppose it is a “Nice to have” item in the API. Shame, as it would be pretty useful, particularly in Dynamo. 
You can however turn it on or off. That’s as much as you can really do though.
Cheers,
Dan
