Hi DePaleRider,
You can rename or delete individual Registrations of a Bank in "Regist Bank Edit" display.
Quote from SX900/700 Owner's Manual, page 89:

You can edit a Registration Memory Bank (delete or rename each Registration Memory, etc.) in the Regist Bank Edit dis-
play.
1 Call up the Registration Bank Selection display, then select the desired Bank.
2 Touch [Menu] then [Regist Bank Edit] to call up the Regist Bank Edit display.
3 Edit the Registration Memory Bank information.
Touch to select the desired Registration Memory. The Registration Memory is selected as a editing target, but not actually loaded.
• To change the name of the selected Registration, touch [Rename].
• To ]delete the selected Registration, touch [Delete].
4 Touch [Save] to save the edited Registration Memory Bank
file.
Best regards,
