Basically, no (as Eric said) unless you roll your own class and forgo 
literal enums (as Lew said).

Personally I'd do the latter.  You should not use an enum for a table 
value imo.  It's an "impedance mismatch" (to borrow a term for 
electrical engineering).  Use a class that is made read only after the 
constructor executes, or can only be accessed by a special package, or 
whatever your requirements dictate.  Rolling an enum-like class is not 
hard, just requires a bit of thought.
