Rearrange new sequence from locked section c

Hi it would be cooler if there was a rearrange chords mode that is played out instead of using the mouse and copy modes. For example locking section C applies to all white keys and then in this mode we could hot some special record feature which plays the chords from the white keys but will rearrange the order as played to create a new sequence of white keys C-C up the octaves.

Not sure if I get this correctly, you would like to set aside a list of chords (here in section C for example) then activate a “re-arrange” mode. You would play chords in a specific order and chords would be copied in this new order further up the keyboard?

Thats it. But may not be necessary.
