Can you adjust Captivate export settings for files that end up in the "wor" folder?

I'm trying to save time adjusting the bottom padding for each of our custom closed captions. (It's code embedded into a Web Object.) There's no setting in my embed code for bottom padding, but when I publish the project, there's a ton of white space below the captions, and you can scroll down enough that the captions no longer show. More of an annoyance for those of us with OCD, because captions still work. You just have to scroll all the way back to the top to see them. I found I could fix the problem by going into each of the files in the "wor" folders and changing the bottom padding from 56.25% to 5%. Is there a way to change the export settings, or is the only way to edit each of the "wor" files individually?
