TimesheetSaved Event

My client requests something similar to what was requested here:

Specifically my client requests that I add a Custom Field to Timesheets which is a Yes/No called "Issue?"  If there is an Issue, the client requests that the Resource is automatically directed to the Task Issue form upon saving the Timesheets.  If more than one Issue was presented, a List of Task Issue forms must be presented.

Is there any sample code on this?
