Option Value into Option Name

[miles]

I created Option Name (color)
then Option Value (white)

Later I created another Option Name (front color)

How can I copy the Option Value which is 'White' to that new Option Name (front color) without creating another 'white' option value.

If you check - values are linked to the option name

Ao you will need to add one or more for the name "font color"
