Use all Membership Pro custom fields on Events Booking registration?

We use both components on our site, and when new users register for an event we would like all of our custom fields in Membership Pro to show on the registration page in Events Booking. This seems like something that should be standard, but I cannot find a way to make it work other than to duplicate the same fields in both components. Is there another way to do this?

Here are two pages for example, one for registering via MP and one for registering via EB:
fasciaresearchsociety.org/membership/mem...r-membership/sign-up
fasciaresearchsociety.org/education-webi...ividual-registration
