While I haven't tried to build your exact design in JMP, the general hub for choice designs delivered via a survey kind of approach is in the JMP Choice Design platform to create the design. Here's the link to the JMP online documentation landing page for this type of experimental design:
The Choice Design platform has undergone some substantial improvements in the last couple versions of JMP so depending on which version you are running, what you see in version 14 may not be doable in earlier versions. Hope this helps.
