Can dropbox be used for visa extension: L-1A Blanket, extended on L-1A individual

I just got my L1 A visa extended as individual, originally it was a blanket. I plan to travel to India for visa stamping, should I consider blanket or individual while booking appointment at US embassy in India.

If your extension of status was approved as individual, you should choose individual.

Thank you, I’ve been trying to get Dropbox appointment but nothing is available.
