AutoCAD MEP 2011 Elevation PreSets?

[jtk07 10]

Can anyone tell me how to save a preset elevation?

 

for example when I place new duct work there is an option for elevation with a drop down and all i have is UCS. I know from the tutorial video that you can name a preset say at 10'-0" but not sure how to do a saved elevation. I have tryed to adjust the ucs and name it but no luck.

 

Thanks in Advance
