Expand Saved->Search function to include searching Notes

i am a commercial guide. There are many times I would like to find a saved hike (Track) based on the notes associated with that hike. In particular I add details about the names of the guests in the track notes and often want to search on a returning guest name to recall the hikes that they have been on - to help me personalize their experience with us. The Saved->Search function currently only returns results based on Track/Route/Waypoint name. It would be very helpful to me if it also returned results based on matching the Notes field.
