Adding store loyalty cards to Apple Pay - watchOS 2

On iOS 9, double tapping the home button brings up all cards stored in Wallet - credit cards and store loyalty cards. This has been really handy for pulling up my Starbucks, Dunkin' Donuts and gym cards on the fly.

I was super excited about trying this on watchOS 2, but when I double tap the side button on the watch I only see the credit cards stored in Wallet, not my store loyalty cards. Is there a way to add my store loyalty cards to this double tap shortcut rather than clumsily navigating to the Wallet app on the Watch?

thanks!
