To start, head over to your Prelude settings through the upper-far right drop down menu.
Once you're in settings, click "Schedule Overview" on the left-hand side.
While here, you're able to input a few nifty specifications:
Group By (Date, Date and Location, or None)
Date Header Format
Single interview Format
Throughout the process, you'll be provided a schedule overview preview (seen above) so you can be confident when saving!
