Almost too flexible and it gets a little bit confusing. Basically, you can add information to the crop marks, AND you can have annotations at the end of the job. The crop mark information is always duplicate of the annotations, and you can pick and choose what you want at the crop marks, but not the annotations.
The Tiling program in Caldera is also very customizable. You can put watermarks in the actual tile with the tile name (A1, B2, etc) or print the tile name in the crop marks or margin. But like I said, the interface is festooned with buttons and controls and it may take some practice to get used to.
Once you find the options you want to run for production, you can at least save them as a preset.
