Thank for your reply John. Maybe I misunderstand you (as English is not my native language), but could it be that one of the registerbanks would be overwritten?
To clarify my 'problem':
Register 1: 12345678 (8 blue buttons)
Register 2: ABCHEFGH
I whish one place (Register 1: (nr. 5) >> to be moved to >> Register 2: on place 'H' (4th blue button)). So, place 'H' can be overwritten, all the other registered places must be kept orignal.
Excuse my ignorance, does your procedure cover this example?
Please clarify what you mean by 'donor-bank'?
