Without actually saying you should "RTFM", this is where reading the manual can help save time, effort, and possibly embarrassment.
Runtime data can already be gathered, but not by default, you need to enable it.
Settings - General Settings - Database - Gather Runtime Data
You can also set a track rating on the device already, however runtime data needs to be enabled prior to doing so for it to have any effect at all.
You can set the track rating via the WPS context menu.
