How do you view specialty player sets that are created?

If someone creates a player set...currently there's a 2012-2017 unleashed player set league filling...is there a way to view these players in advance of signing up for the league? For this one, i suspect is it all the players who were included in the 2012, 2013, 2014, 2015, 2016 and 2017 leagues, including unleashed players, but would like to tell for sure. Do you have the option of all player cards, such as Anthony Rizzo for each of these 6 years, or is it just one card?

If you start a new team and then select that player set, you can look at the players and set up your draft list before entering the league.

I don't know how to look at a specialty player set otherwise (although someone else may)
