How to make Windchill show the role users in the routing tab in a workflow?

Hello all, I hope you are well and safe.

Anyone of you knows how to make Windchill show only the users from a role in the routing tab, while creating a task, in a workflow? What I want is that the routing events showns  the name of the people assigned to a specific role, so I only have to change the users in the "Team" Context and automatically the workflow will update and show the users available to assing the next task. 

Is this possible using some Jaca script?

I was thinking in another option: restrict the users available to re assign a task base on role, so the responsible user of the current task will see, in the re assign list users, the users that belong to a specific role only. Is this possible to?

I will like to thanks in advance to any who read this post.
