mac os x sharing icloud calendars but not reminders

My wife and I each have a calendar and reminders set up in separate iCloud accounts and we share these with each other. On our iPhones we can configure things so that we each can see the other's calendar but not the reminders.

This does not seem to be possible in Mountain Lion as calendars and reminders are combined in the settings.

1. Is there a workaround so that my wife's reminders do not pop up on my machine and vice versa?

2. Is there a feedback page for Calendars and Reminders?
