I have about 100 blog posts and I've been successfully creating 'Page Templates' with ease - and when I create a page I can select the Page Template from the 'Page Attributes' which is all very nice and easy.
I thought the same would be possible for posts...
So I created a post template and saved it as 'single-template-1.php'
Having uploaded the Post Template I notice that there 'Post Attributes' dropdown isn't there so I cant select that template.
Any idea what I could do to fix that?
