Using Pay with a Like in Membership's protected content editor

I'd like to add a pay with a like wall inside the membership plugin's protected content wall (the one you put between shortcodes). This is to give those who share a coupon code to use with membership.

At the moment, any pay with like shortcode put into the protected content editor (Membership > Options > Content Protection) posts the content I'm trying to protect.

Being able to do this is the ideal set up. Otherwise, I need to link them to another page to get the coupon. Thanks!
