add styles to inputs if they have a value

[PROda221]

Hello developers!
Need a prop through which we can get to know if boxes has a value in it or not. With this we can style specific boxes if they have a value present on not. If this already exists, then please let me know

in the image I would like to darken the borders of all the boxes if they have any value present in them.
Like this :-

Also is there a way to add __ at the bottom of every number?

Thanks!

Waiting for this feature. We need a way to know if the field has any input value so that we can change the style accordingly.
