Using Catalina and BigSur on one MacBookPro with Boot Camp

I want to use Big Sur beta but I want also using macOS Catalina on my MacBookPro.
I am wondering if I could use Boot Camp to run 2 versions of macOS on one hardware (MacBookPro)

Who has experience with Boot Camp running 2 versions of macOS?
Boot Camp is used to install and run Windows 10 on Macs, not macOS.
