Workfront Boards - Allow filter by custom user field.

Enhancement idea to add WF Boards filter (on the left hand side) to allow to filter by custom field.

We have a board with advanced input filter (in the board configuration) that pulls in cards from a custom field that is a user field. While this pulls in the right cards, it doesn’t allow the left hand side filter to filter by the custom user field. The idea is to allow a left hand side filter to be setup, similar to how assignment would work. This would allow users to just see their own cards. 

Let me know if any questions.
