Make two results pages with different cms sort

I’d like to sort my data in 2 ways. One page would be by alpha sort of members by last name.
The other would be a random sort - I’m OK with making a field with random numbers and having it sort using that field. But, how can I do this? make a second CMS collection, somehow make a second results page??

OK, where do I find the results page? Is it under Dynamic pages? I don’t see that layout there. There is one in the regular pages called Members/CS Design Page, but I don’t see where it’s sorted. The CMS file has a sort - I’d like to sort other pages differently.
