Request for categories for "Terms with manual transliterations"

We currently have Category:Terms with manual transliterations different from the automated ones/hy and Category:Terms with redundant transliterations/hy and such. I'd like a category Category:Terms with manual transliterations/ar (and possibly similar categories for other languages not in override_translit, but for the moment mostly I care about Arabic). This would be useful because most manual translits for Arabic can be removed by using the manual translit to vocalize the Arabic properly and then removing the manual translit. I have a script to do this but it doesn't currently have a category to operate over. Thanks ...
