Took some (one time) preparation effort, but here’s how I “unlocked” the sound-pool for my workflow.
- Use the Elektron Transfer-App to backup all sounds on your PC.
- Clear/Wipe the pool completely.
- Load back the sounds (with the transfer app) in an organized/per bank way. I chose to sort “instruments” per bank, meaning:
Bank A= all the kicks, Bank B= all the snares, Bank C= all the claps etc…
That way if I am looking to change the preset on my snare-track for example, i can simply select the corresponding bank and browse only suitable sounds.
In addition: I think it’s good practice trying to keep certain instruments on the same tracks across all patterns anyway…
Hope this helps 
…and keep in mind to save new sounds to the correct bank for future convenience.
