question about new calendar events

[wmscottmc]

On my DX, when I create a new calendar appointment, there is a field name "Who" to allow me to invite others to the event. I dont see this same field when using my calendar online. Maybe "Add Guests" is how it is done online.

Is there a way to disable this field, on the phone. I dont need to invite others to my calendar events, and this field is just in the way, since I dont use it.

Thanks
