A lot of controls won't run a G53 without the G0 in the mix ether in a line before or on the same line like G0G53----
What reference are you using that says G00 and G53 are exactly the same? All those I've read say G00 is a rapid move in the current work offset coordinate system, and G53 is a feed rate move in the machine coordinate system.
Can't customize the post processor? Wow. I have only used a few CAM programs, but they definitely allow me to modify or create a new post processor. One I use even allows a script system to modify the code after the post processor is done, and its a cheap CAM program (under $200). Still haven't used most of the high end CAM systems. I guess they could be more limited, but Fusion which is arguably not low end allows for custom and new post processors as well. Further many CAM programs allow you to create templates or styles and libraries of styles. Often you can add customized header or footer code to your styles and when you apply a style (or template) to an operation it automatically applies that header and footer code. In one Cam program I use I just set universal things in the root style and all other styles in that library inherit those properties unless they are changed.
