How to upload section in one doctype from another doctype

Suppose I have 50 fields in one doctype and I need to create 30 of them in another doctype… is there any way, I can export that section and use that same section in another doctype.

@niraj_regmi You can do one thing just copy to clickboard and remove the fields which you don’t require and just save the doctype.

that will create another doctype i don’t want that I just want to reuse the section of one doctype to another
