Admittedly I've never used the add-on MS performance dashboard reports, but are they standard RDL files? If so you can publish them to your report server and setup a Subscription to email them to you at a set time each day. You'll just need to configure the Email portion of SSRS, but doing that doesn't require the service to be restarted.
If these reports are only accessible through SSMS by right-clicking on the DB and choosing Reports, I'm not sure there is a way to schedule those directly.
Update: I found an article showing how to publish these reports to SSRS. It's referencing SQL 2005 and 2008, but I assume this will work just the same on 2012:
