Is there any way to use external templates?

Hi All,
I am wondering if is there any way to upload external(not selling in webflow marketplace) HTML templates in Webflow?
I saw a topic about it but it was from 2015 so is it possible now or not?

Thank you.

Unfortunately you aren’t able to import templates into the Designer so any templates would need to be purchased from the Marketplace.

thank you for response!
