Bypassing SLA when using technician scheduler?

Bypassing SLA when using technician scheduler?

Hello,
 I am using the technician scheduler for PTO days and assigning a backup technician for that day. I noticed that a week prior to that techs scheduled PTO, they were not receiving ticket assignments that had an SLA due on that PTO day. Is there a way to take the SLA due date out of consideration when assigning tickets to technicians?
