CSV Importer & content with specific fields

Hi all,
I’m starting with a new wp site where I’m in need to import hundreds products into pages or posts with custom template. Some of these datas I need to put in specific fields inside the page or post content. Is it possible? Does the importer manage the custom fileds inside the content?
Many thanks
