Programming language in Atom in specific Atom directory?

Question

atom

Is it possible to change the programming language in files with the desired extension in only one, specific directory? That is, for example, there is a directory "project/", in which there are a bunch of files '.py', '.html', '.sass' files, atom defines them immediately as, respectively, 'python, 'text.basic.html', 'text.css.sass'. So, I want '.py' files, only in this directory, to open under another programming language ( 'python(django)', and '.html' files under 'html(django)'
