Search bar in playlists while using USBs/SSDs on DJ equipment

I use an Opus-Quad but I think this could be applied also in other products. Is it possible to add a "Search bar" in order to look for a song ONLY in that specific playlist (and so the research wouldn't be on the entire library) while using USBs or SSDs? This doesn't mean that I no more want the search function that covers the entire library, but it would be useful to add a function (I don't know where) which let you look for a song only in one specific playlist
