Subtask's showing up on Kanban board Question

[Stephanie]

Can anyone help with having a sub-task's show up on an assignee's Kanban board.

Here is the scenario we run several different teams; the epic and story the sub-task is associated with is assigned to one team (lets say team A).

Team B needs to work the sub-task but not the story or epic.

Can I display only the sub-task on the Assignee's Kanban board.  If so how?

I tried to label the sub task with a dependent team and shared service team but it still is not showing up on the Assignee's board. The developer still needs to go to team A's board to look at the sub-tasks. 

Thank you in advance for any help!
