Searching for a score in "sets" / 'My Sheetmusic'

Hello,
I got a question from friends: "How can one search for scores in my sheetmusic or/and in my sets of scores?
I know there is now a possibility in 'Sets' to search by titel, newest, oldest set, but not for searching at a certain score, once you selected a set, without having to scroll through the whole set.
This would be very usefull for people who are searching for that particular score in a big set. Also because many pf mu scores are ordered as they appear in the original book/manuscript (seldom alphabeticaly).
Please some respond, or help ..
Johan
