Display two calendars side by side

I have an administrative assistant who manages calendars for two company executives. She would like to be able to display and manage both of their calendars by having them appear side by side so that she can compare them when necessary. I know I can create a new home page with two applications and accomplish this for her. That works pretty well, but it is a bit cumbersome since she loses her own home page at that point.

I could possibly create an application that would accomplish this but I was wondering if anyone could think of a way to do this within the Notes client without doing any development?

Thanks for any suggestions you may have.
