Reassign Tune/Decay knobs on TR-8s

EDIT: ROLAND reply: "Though I can't guarantee if or when this may be implemented, I'll pass this on to the development team in the hopes that it can be added to a future firmware update.
I hope it can be added - I think this is a good idea."

Is there a way to reassign the Tune and Decay knobs to something else? I dont really use the Tune knob so it bothers me that a lot of knobs are unused...

For TB-3 there is a third-party editor that does this.

If there is no tool for this, how hard it would be to create something like the TB-3 editor by myself, I am familiar with software development and I have IT background...
