Allow other attendee to input info

I would like to suggest a feature to be able to use while having a meeting in WebEx:

To be able to share my screen with the other attendee and allow them to enter information on that screen. For example, I'm having a meeting with someone and setting up online accounts for them. The accounts need the attendee's social security number and credit card number. The attendee doesn't feel comfortable giving me that information to type in myself. Allowing a feature to have them confidentially input it themselves would be very valuable.
