how to schedule bank holidays into a daily backup plan

We have a tape backup plan running daily, but we want to disable it for days when the company is closed (tape inserting is manual). So basically for all bank holidays.

In other tape backup softwares (for example Symantec) it is possible to schedule interruptions for backup plans, there is a calendar tool to select the days when it should not run, without having to edit the backup plan itself.

How can we achieve this with ABR ?

Thanks in advance
