Scheduling Reports

[SHA]

Hello - I am not a developer, I am a user and am hoping to get some guidance.   I use Cognos Analytics 11.0.13.1 - I run certain existing reports and would like to schedule them to run automatically for me every day.  The report however requires the user to select the date to be run each time.... therefore when I try to schedule the report, it will only give me the report run for a specific date, and run the same date each time.   How can I schedule this report to run for me every day automatically updating the date selection to the current date?

Somewhat related question, what is the difference between scheduling a report and subscribing to a report.
