301 Redirect Wildcards?

Hello everyone! I was setting up 301 redirects from an old website to a new website and ran into an issue. For SEO purposes I need to send people from one specific page on website A to website B so that the page rank and rankings transfer from one page to the other (ideally of course). The problem is that there are hundreds of other pages that I want to send to the homepage and it is a nightmare to try and identify each of them. I tried to use a wildcard but that overwrites all of the other 301 redirects. Is there a way to list all of the 301 redirects and then send the rest of the pages to the homepage for any that were missed?
