Exclude a person from a team "Apply Assignment Rule"

[Emmker]

I have created a "User on leave" filed in the User entity.
I have to make a workflow that distributes the Cases of a User, when he is on leave, to the other users of his team.
I made a Report to gather the Cases that have the assigned user on leave.
I made a workflow that runs every hour and has the aforementioned report as the base.
But in actions, when I use the "Apply Assignment Rule" I can assign the Cases to the team, which includes the user that is on leave.
I cannot find how to exclude him from the case distribution.

Any ideas?

Just remove User A from Team B for the duration of his vacation. Then create a Task with a reminder of his vacation end date to bring back User A to the Team B.
