Calendar - Make Hour-by-Hour Grid in Week View Collapsible

When using the Week view layout in a Calendar report it has an hour-by-hour grid for each day of the week. When objects without a time don’t fall into these hour slots the hour-by-hour grid shows blank, taking up a lot of empty space on the page. I would like the ability to hide, collapse or turn off the hour-by-hour grid when viewing a Calendar report when the hourly grid is empty or unused.
