Flatsome "blog" template option

Dear Author,
I have a question regarding the template function of the theme.
I have a lot of “blog” articles to write down, they are almost the same structure. So I wrote one and get it published. I found the Flatsome could save it as a template, for future article use, with the same template but different content.
When I write a new blog with UX editor, it does not show an option to import my own saved template, but only from the flatsome studio.
When I tried to write something in the “page” part, the option comes with a “custom” block, which contains the template I saved.
May I know if this the own template option is only for “page” but not for “post”, then that’s strange because I can save the template in the “post” page.

Let me know please.

Is there anyone can help with?
