I would like to take an array of X length and return X individual process variab

Michael, the challenge here is that PVs are not created on the fly. Can I ask what your original use case is? Maybe we can take a step back and approach the problem in a different way.

Alex,
I want to create a list of people that are all in a single group, and use that list to populate the facet option that I present to select them. I can display group members from a group that only has single members, but get a list back from some of them, I also would like to populate different facet options with items from multivalue constants that I use to select products in an application.

Michael, facet options are not dynamic at this time. For more on this please see: forum.appian.com/.../Record_Design

You could however consider designing your facets to accommodate the names in the example here: forum.appian.com/.../Record_Design
