Different policies

Hi,

I'm running NBU 7.6 and I need to backup some files with 2 different retention period.

All the weekends the job will run with the retention of 2 weeks and only on the last weekend of the month the retention needs to be infinite.

We current have two jobs doing the same job but with different retention setup.

My question is: as the job is pratically the same, is there a way to have only one job and after the last weekend of the month just change the retention of the tape? (I know how to do it) I'm just wondering if there is an automatic way to do it or what would be the best practice in this case.

Thank you very much.
