Hello,
Sorry, but we don't understand your question. If you need to replace placeholders you can use the template methods available in the library (https://www.phpdocx.com/documentation/practical/working-with-templates).
If you need to customize the bullet points of an existing list you need to use DOCXCustomizer (https://www.phpdocx.com/documentation/introduction/docxcustomizer).
If you post more information we'll be able to provide further help.
Regards.
