Visualize the 'unique'ness of a certain table field in the diagram

How to visualize the 'unique’ness of a certain table field in the diagram? I know that using the ''unique" keyword we can declare unique fields, but how to see that on the diagram?

Currently, we don’t display the unique indicator on the diagram.

I turned this post into a feature suggestion so other users can vote for this. We’ll consider displaying an indicator for the unique index in the future.

Thanks.

We need this feature.
