Overriding module pages?

[TheHYPO]

I have added a new field to the product SQL table which I want displayed on the product_info page; as a result, I need to create a new variable in the main_template_vars.php file for the product_info module (modules/pages/product_info). Is there a way to properly override a pages file?

I have properly overridden root modules files in modules/CUSTOM (custom in place of my folder name), and I've tried every logical override option I could think of, including:
modules/CUSTOM/pages/product_info/[file]
modules/pages/CUSTOM/product_info/[file]modules/pages/product_info/CUSTOM/[file]

None of which worked (replacing the file in its original location does work, so I know these are not working. Is there any way to do this or do I simply have to override the original?

Thanks.

The overrides framework doesn't support these changes. Be sure to make a good backup so you can compare with the original in case of problems or during upgrade.

Thanks for the quick reply. I'm used to making changes, this is my second time building a zen cart, so this time I'm making sure to thoroughly comment any changes I make so they are easily locatable if the file should ever be updated in future zen carts. I obviously prefer to use the override whenever possible, however.
