I've added a custom field for defects named "Project Manager".   It is tied to the Users List Pick List.

During the process of adding/editing a Defect or Feature, this works as intended.

The problem I am having is when I attempt to do a filter based on that custom field.   When adding a filter line item, I select the custom field, and the filter type changes over to text - and only lets me check for "=" or "like".   I want this to work like the [Assigned To] field in that it works with the [CURRENT USER] token.    Am I missing a step in making the custom field recognized as a list by the filter area?
