Currently, creating chords using custom hitsounds requires custom sampling of each chord individually (or incredibly complex hitsound naming schemes). If your map uses 88 piano hit sounds named normal-hitnormal through normal-hitnormal88 it is impossible to use two of those hitsounds at the same time. The one current workaround that exists is to manually sample the hitsounds you want to use into a single hitsound. Some songs use a huge amount different chords which can quickly take your map over the size limit (and take a ridiculous amount of time to manually create).
Sometimes it is useful to have hitsounds that are assigned to multiple sample sets (eg a normal-hitnormal sound might consist through a section using soft-hitnormal samples for claps/whistles/finishes). It would be nice if you could assign sound files to sample sets, not the other way around.
Solution: Allow the user to select any number of hitsounds from within the song folder without limiting selection to notes in the current sample set. This feature would probably (most certainly) be an osu!next thing so I'm sure there's a simple, elegant solution that the team will concoct.
