Show free shipping and weight based shipping by default in add new product page

Hi,
I want to display Free shipping and weight based shipping by default in vendor add new product page -> shipping tab. Currently i’m using WCFM shipping rules (weight based shipping) Yeah i read the documentation about this, it works https://ibb.co/FwhjTp4 i got this result BUT here vendor need to add free shipping method in settings -> shipping.. to be shown in the add new product page. But i don’t want vendor to make this process hard, So i want this to be shown by default as this https://ibb.co/FwhjTp4 to every vendor. I’m an ultimate user posting this question here because premium tickets taking so long to reply. #316112. Wishing for a solution here

Regards
