Redmine

I'm trying to create a Wiki in Redmine that I can also use as help screens for my software. The problem that I run into is that the folder structure for the wiki is flat, so if I have a structure like Accounting\Leger\General_Information.html and Accounting\Budget\General_Information.html I can't have two pages named General_Information in the wiki. I tried the trick of renaming the first page to Accounting_Ledger_GeneralInformation, but when I create the second page the first page shows up and I cannot change the data on the page without making changes to the first one. I've noticed that a few wiki pages have a wiki\1\pagenamhere, but could not find any way to change the directory structure or enable it. I'm running BitNami Redmine Stack 1.0.2-0 on Windows Server 2003.

Here's what the Bitnami Stack setup includes:
- Redmine 1.0.2
- Apache 2.2.16
- ImageMagick 6.5.8
- MySQL 5.1.50
- Subversion 1.6.12
- Ruby 1.8.7-p249
- Rails 2.3.9
- RubyGems 1.3.7

Any ideas or workarounds would be greatly appreciated.
