Way to Set Default Delivery Method?

[Ron Serio]

We're setting up a series of parameterized URLs to take users directly from a webpage into specific Cognos reports.  Mostly this is working fine, however, one of the reports takes a (relatively) long time to run, so we'd like the output to be e-mailed to the user instead of them waiting to view it in the browser.  I've had several ideas on ways to theoretically solve the problem, but no knowledge of if they are actually possible.  Can any of these work:

• Set the default delivery method on the report to "Send me the report by e-mail".
• As part of the parameterized URL, pre-select the delivery method.
• Use javascript in report studio to switch this report to the e-mail delivery method.

I'm also all ears if someone has another idea. 

We are on 10.1.1.

I apologize if this isn't the proper folder for this question.  Thanks for any help!
