Kanban Board - Why we can't select a Subscription Admin as a card owner?

Issue/Introduction

How come a Subscription Administrator isn't appearing in the user list for Owner in a Kanban Board card?

Environment

Release:
Component: ACSAAS

Resolution

Only Team Members can be selected to own artifacts. That is the behavior not only for Kanban Board but for any app and also for the product screens. Even a Subscription Administrator can not be made owner unless is added to the team.
