A hypothetical situation:
I have product features. These features are stored as BITWISE values in the database.
In my back-end code, I have a [Flags] enumerator that lists out all the features with its bitwise value assigned to each item in the enumerator.
This, obviously, gives us great benefit from a coding perspective, and, not to mention, faster I/O and fewer database records.
However, now I want to give someone the ability through a CMS interface, to add a new feature to the features table. Let's call it "Feature7"
So, "Feature7" gets added to the table with the next bit value assigned to it in the database. This is the 7th feature, so this will have a bit value of 64.
But now, the problem is that the [Flags] enum has to be manually updated to include the new feature and its new bit value. Which, doesn't really make the management of Features from CMS "automated"; there's still manual intervention needed from the developers.
So, my question is, using BITWISE, is there a way to make this fully automated without having to have code that generates a new DLL every time features are added to the table, like is suggested here:

Let me know if that makes sense.
Obviously, I know this doesn't need to be done using bits, so I don't need suggestions in that regard.
Thanks in advance!
However I usually don't use bitwise operators when the end user may need extra features. I use a 1:n relation in two tables. One table has the key value plus a user description. The other table just stores the key along with the individual items.
