Lowell, thanks for the reply.

You can create default constraints, but it doesn't appear that you're allowed to name them. It's the naming part that I'm looking to accomplish.

Actually, right as I was notified of your reply, I was testing out using sp_rename to change the system-generated name to something more standardized. Every indication at this point is that this will work. I just need to work out how to do this on a whole database without hard-coding names.
