OS: 4.2.2 In Samsung Galaxy Tab 3, not rooted.

Folks, I'm trying to set custom locale in a tablet. I tried it using the app 'More Locale 2' app. It works fine, it set the correct locale.
But it also set the numerals to a format which is out of use. I want to keep the custom locale and want to set only the numeral system
to 'Western Arabic' i.e the normal 0,1,2,3,4...etc.

Is there a way to achieve it?

Thanks.
