I don't think so. They have to all be stored in the config because you 
have to write them all out when you write the config. It makes sense to 
me to keep them all in the config and read one of them instead of having 
2 places with the value and possibly having a bug because they are out 
of sync.

If I'm misundersstanding your comment then let me know.

Yes, the value doesn't change between the 2 calls so no need to set it a 
second time.
