Yes, the way how to do it is described in STORING A PRESET section of the manual:

To rename the edited Preset and store to the current location:
• While the Preset name is flashing, press & hold EXIT/STORE again briefly until the Preset
name is displayed with the cursor flashing at its first letter
• Turn the PRESET selector to change the letter or character.
• When you have found the letter or character you want, push PRESET to select it. The
cursor will automatically move to the next character.
• Repeat until you have renamed the Preset.

The Section Switches act as naming shortcuts:
PRE FX - Clear
AMP - Number
MOD - Upper / Lower Case A
DEL - Upper / Lower Case
REV - Space
POWER - Backspace
CAB - Cancel


• To complete the store process, press & hold EXIT/STORE once more until STORED
appears on the display screen. Your edited Preset has now been stored to CODE’s
memory.
