How to display attibute slug in backend attribute dropdown

Hi,

I’m looking for a way to display attribute slug with the attribute name in attribute dropdown from Backend – add & edit Product – Attribute dropdown

The reason is because the site is selling yarn and have multiple attribute called Color with different slug (one for each collection) around 50 collections.

So in backend when I want to add the color attribute to a product I will have many attribute called color so this is hard to find without the slug.

Any suggestion or code snippet is welcome
Thanks
