H4 dates to be changed using TTS

[sharmapa]

Hi,

My wife has an H4 appointment later next month. I had taken an appointment for her thru' TTS. Can I modify the appointment now using TTS website or do I need to follow the VFS route? (ie cancelling the TTS appointment and applying for a new appointment via VFS). Has anybody modified their TTS appointment after VFS came into picture?

Thanks in advance for your help.
