Add Contact into PhoneBook at Mobile Display

I find this feature is very important for Business Directory & Directory Theme

During Mobile user visit the listing, if there is a 1 click feature/button to add the contact into phone book, it will be great.

During I share the listing to to some one over mobile, the person only able to view it, and unable to save the contact in a convenience way, he/she had to manually save the contact into phone book.

Hope this feature available soon, this really make people life simple a lot.
