Only adding new icons to the file?

Hi, Is there an option to only add new items to the output file from create-chakra-icons not generate it from scratch every time? I'm asking this because I have many icons and I'm wondering if I can skip commiting them in git. If we have the option to only extend the output document, other team members will be able to add icons to the document without having the original svg of the previous icons.
