Well, you could knock me down with a feather!
I didn't know that the DataAssist options were there. I know the other tools are there because of their naming convention being WA... or WebAssist... but I didn't know that DataAssist was in there too! I thought I was limited to the wizard, the search wizard and the repeating table options.
There are quite a few options in there... looks like I have a bit of learning to do!
