Hello Allen,
You can just use the native CODM format to create your own version. This just requires a text editor or an XML editor of which there are many free versions available. Since you plan to simply update the layout and not add functionality the MySQL option wouldn't be worth it I feel since you would need to purchase a license from us and then learn the formatting which is much more involved than the CODM format. Thus, in my opinion, you are better off copying the current CODM file to a new file then editing that to create your own layout.
