I think the issue is that there should be an option to pick a day of the month. For example, I want to run my tape job on January 1st, February 1st, March 1st, etc... but that is not an option in the scheduler. I can't select Monthly -> First -> Monday because in 2016 that would be January 4th, February 1st, March 7th and so on. A really nice feature (which I believe has been requested numerous times) would be a calendar scheduler, or something similar. That way I can pick the specific dates that I want my tape jobs (or any backup job) to run.
