If you are rebuilding the bridge cache from scratch, it would be valuable to allow and option to allow you to specify the "Generate monitor-size preview" monitor size. This would be very useful if you are using an alternate machine to generate the cache. For example, if you have a very large cache (500,000+ images), the process could take a week of processing or more and it would be useful to do this on a second machine (such as a laptop) which has a smaller screen than the main working computer. For example, the desired monitor size on my processing computer is 1920 pixels wide, however my laptop may have only 1024 pixels. By allowing a monitor size specification, I could specify that the preview images could be 1920 pixels even though the actual build computer would have only 1024 pixel screen.
