To detach a specific instance of a symbol from the parent symbol, you can use the 'Detach Symbol' option. When you detach an instance from the symbol, any changes made to the symbol will NOT affect the detached instance.
1Select the symbol and click on 'Detach Symbol.'
2A confirmation alert will pop up; click OK to confirm.
To simply edit certain aspects of the symbol like text or icon without detaching from the parent symbol, you can use the Edit instance option instead.
4Note that changes made to the symbols will not affect these detached instances.
