Suggestion

Hello, I created groups through the tool of your app, very interesting and practical, however I have more than 4 thousand contacts in my phonebook, and to create groups, contacts one by one, lose about 5 days, I would like to know if it is possible , you put the option to export contact strips on vcard or via email account, and group them all together, if it is possible to create this tool, you can charge a fee for your app, which I and many people, will pay.
thankful....
