You can give labels custom names that do not depend on the disassembler configuration. Those names are defined in the file CustomLabels.ini (one for each edit mode).
<label offset>=<custom name>
If the disassembler finds a label at the specified offset, this label gets the custom name.
To find offset values, enable the CODE_OFFSETS debug option. After disassembly, the number displayed before each script instruction represents its offset value.
