Is there a way to have multiple Exchange Calendars on the Pre without having Tasks and Email also come over?

I find I need to have coworkers calendars show on my phone so I do not make appointments when they are otherwise engaged, but I don't need their Task info or Email accounts. If I delete the account in email, then the calendar goes away as well.

Any work arounds or am I missing something very basic (totally possible).

Many thanks in advance for any insight, and apologies if this has been covered in another thread. I did look but found nothing similar.
