How to make an add array elements public variable

[Architect3D]

Hi, I’m having trouble getting the interptomovment blueprint component to expose the add controls points array element as a public variable.

Ive included a screenshot of the current blueprint code and how it looks publicly, basically I’m stuck having to, before hand, create all the possible elements. The third pic shows how I would like it to work. Which is basically adding individual elements incrementally.

Did you ever figure this out? I’m trying to find out how to do this as well. I have a Text Array variable that is public and I want to add more elements to it but through the details panel publicly.
