BI Reporting Scheduling and Options

Summary

General questions about BI Reporting.

First, I have several scheduled reports that trigger notifications, forms, and other processes in my companies HRMS and Task Manager applications.  I am curious if there is a way for me to forego the 90 day recurrence expiration.  I need these reports to run indefinitely without me having to touch them every 90 days.  Is there a way to have support turn that off?  Or bypass that?

Second, my management team would like a report that shows past due percentage.  I haven't found a report that runs based on past due information.  I can pull all incompletions, but then I have to manually sort and filter to find the ones that are past due.  I can't imagine that I am the only one running into something like this.
