UNC as Custom Field Type

[lonelyadmin]

I added a UNC option as a custom field type. What would it take to make that value "clickable" when viewing the asset?

Added in app/Models/CustomField.php
'UNC' => 'regex:/^\\\\\\\\[a-zA-Z0-9-]+(\\\\[a-zA-Z0-9~!@#$%^&(){}'._-]+([ ]+[a-zA-Z0-9~!@#$%^&(){}\'._-]+)*)+$/',

I'm guessing it's just adding the file:// before the ${UNC}, but I have no idea where to do that. Or, does URL regex need to be tweaked to handle "file://"?
