This is probably not going to happen without an API add-in. I've run into this before and created an add-in to do this because Dispatch cannot change variables to upper or lower case.
- If urgent and important, then an API add-in task can be written to run every night at midnight to bulk update card variables.
- If important but not urgent, use a right click API add-in menu to update the variable on selected files. Touch fix
- If neither urgent nor important, no action required except to update the card variables during transitions using an API add-in. Ongoing.
- Not sure how you want to handle configurations, but that is a BIG consideration.
CAUTION: Editing the SQL database directly is NOT recommended and NOT supported. Please do not consider doing this as an option.
We have a paid add-in that does this. If you'd like more information, PM me. We also have lots more add-in products that may help you.
Hope this helps,
