Different registration fields per ticket class?

Different registration fields per ticket class?

I saw on this post that 3 years ago it was not possible to have different registration forms or fields per ticket class, but an agent replied that it is on the roadmap. I'm wondering if this is possible yet.

If not, does anyone have suggestions. We want to offer a ticket class for our association members, and another ticket class for non-members. Typically we would have members prove membership by providing their member ID number. This member ID field would only be visible for the member-discounted tickets. Is there a way to do this in Backstage?
