Setting up wpmu to automate the Front Page Displays

Hello,
I set up my install of wpmu to automatically create 5 static pages, which it does beautifully. Two of those static pages are titled "Welcome" and "Blogs." My goal is to then have the system automatically choose the "Welcome" page as the default Front Page and the "Blog" page as the default Posts page. As you know, this can be done manually by the user through "Settings > Reading > Front Page Displays, etc. But my goal is to automate that process. I did try the "New Blog Defaults Plugin" but did not have this feature. Any help would be greatly appreciated. Thanks for your time.

Best,
Terence
