Can I create additional forums pages in BuddyPress?

I have a membership site that has been up for almost a year that uses the BuddyPress plugin for discussions. The forums have gotten out of hand with almost 1,500 new topics, each with anywhere from 10 to over 100 comments and 25 groups. This makes it almost impossible for new members to navigate through the different topics.

Can I make sub pages under the forum pages to help organize things? I hope I don't have to host a new domain name for each one.

Thanks,

JoAnn
