I realise that there is a documentation on Apple, suggest that we can create our own custom SF symbol. https://developer.apple.com/documentation/xcode/creating_custom_symbol_images_for_your_app
I have tried to follow the steps, modified the "Regular M" node. May I know if I need to modify all the node one by one? Or there are some way to automatically generate the other sizes after modifying the "Regular M" node?
Example, the sf symbol "textformat.abc.dottedunderline". I would like to change the abc to 'efg'. Is there any automated way to generate all sizes?
