Dependent select list - Project Role - Assignee

Question

Has any one figured out how to create a dependent select list using Project Role -> Assignee or Group -> Assigne?

I need to be able to set an Assignment Group and generate a user list based on the role (or group) selected.

It should work like this:

Field A - User selects Proejct Role.

Field B - Displays a list if users in the role selected in field A.

Field B must be optional. Projects will use Field A as a queue and will assign based on priority.

I was able to get the needed cascade selects through the use of two plugins and workflow post-functions.

User Picker from Project Role and Dynamic Forms

I then used workflow post-functions to copy the selected user to the Assingee field.

It is a bit clunky, but it works (for now).
