I believe that anything you could manipulate in Revit in the core UI should be able to be manipulated in Dynamo. Without actually trying it myself, I'd run with the following assumptions based on what I know...
1) If you can't schedule it in Revit, Dynamo likely can't access it.
2) If you can't change it from the Revit UI, Dynamo likely can't do it.
3) If you can do it via the Revit API, Dynamo might be able to do it but you'd likely have to build some custom nodes.
4) If you can do it via COD Script in the other Fab products, Dynamo likely can't do it.
5) If you can do it from the Fabrication API, Dynamo likely can't do it.
