Implode to particular instrument or new instrument

While the implode feature works very well, I don't think it's always ideal for the top staff to also serve as the destination for the imploded voices. It would be great if the implode feature could be expanded to give the options of (a) choosing a destination instrument or (b) creating a new instrument as the destination. This would save a lot of time in some cases, i.e., creating a piano reduction.
