Different Display Settings for Different Calendars?

[charmedhour]

I have two calendars on my site: One for upcoming events and one which is a type of "This day in history" calendar.

The upcoming events show up a few days ahead of time, per default. However, I would like the other calendar - "This day in history" - to have the event only show up on the day-of (as birthdays do). I cannot find a separate setting for this; all I see is the one under vBulletin options -> Forums Homepage Options -> Display calendar events? That only gives me one option for both calendars.

Is there a way to differentiate this prior-days-forum-display setting from one calendar to the other, or do they both have to be the same?

In addition, can I create different forum bars for different calendars - the default in the forum bar titled "upcoming events" and the additional calendar with its own forum bar, displaying the "This day in history" title?
