Modify cut/fill slopes after grading

[clepine]

Does anyone know if it is possible to change the slope after grading. I have graded an oil drill pad with 1-1/2:1 cut/fill slopes and the client would like to see the fill slopes at 2:1 to reduce spoil. I know you can set different slopes for the cut and fills while creating the grading surface but can't find a way to modify after its graded. Any help is appreciated.
Thanks

I'm new to Civil 3D myself but have been working with gradings recently. Why don't you delete the grading and redo it with the correct slope?

Yeah that is what I ended up doing and because I'm lazy and don't want to redo a finished product, it would have saved me half an hour by not having to recreate the pad and cross sections. With all the ways many you can modify a grading surface I just hoped there would be a way to change the cut/fill slopes.
