Add custom filters to report schedule

I have a financial report (Income Statement) that I want to email by schedule. I set up the schedule with recipients and time etc. And then I go to Reports -> Scheduled Reports -> Report Schedule. Here I click “Customise” next to my schedule.

The only filters I have to choose from are the ones that are standard in the report. I don’t see all of the other filter columns I have added to the report. I would like to have different recipients getting the report filtered by certain departments.

On the customise report schedule page there is a text: “Only filters defined in the footer of saved reports can be customized for this schedule”. Does this mean only standard filters? Or is there any way I can add my department filter to the schedule?
