New Interview Schedule

Hi,

Is it possible to hide whole section of "Notifications sent to candidates" on the New Interview Schedule page (please see below). We managed to hide individual notification fields but the header stayed in the page.

Also our interviews are defaulted to 30 min. Is there a way to change this to 1 hours. We tried many options in VB but were unsuccessful.

We need to remove section in yellow:

We would like an interview to default to 1 hour (currently 30 min).
