ability to pre-populate a work item description field

I'd like to be able to have my users create a new work item (specifically, a defect type) and have the description field pre-populated with a textual template.

The text would give the user guidance on the information which they should be providing (OS, hardware, steps to reproduce, expected behavior, actual behavior, etc.). I had this capability set up with an older Bugzilla system and it really helped to reduce the time that a defect owner had to go back to the submitter with requests for additional information.

Is there a capability in Jazz/RTC that I'm overlooking to accomplish this type of customization? I'd prefer to avoid having to create lots of special input fields in the editor presentation if possible.

Thanks, Jim
