Hi Brandon,
You can set patterns for your numeric field. Click your field, on the Object palet's Field tab, click "Patterns" button. Set Data and Edit tab's Pattern area as num{z,zzz,zzz,zz9}, Display tab's Pattern area num{z,zzz,zzz,zz9'cc'}.
So that while editing and on data exchange your numeric field send as numeric. However while displaying the field it put "cc" at the end of numeric field.
Hope this helps.
