Add Option to Dropdown

Please take a look at this form http://www.jotform.us/form/50395241022141

In the auto complete box that is asking to choose your name.

I asked that a feature be added, where a user (a person filling out the form) can add their name to the list and their name will be saved for the future when they come back to sign in.

For now i am doing manually as you can see there is a box saying please add me to the list by clicking on add option.

Wondering where you guys are with the implementation of this feature.
