Assigning modified Twig templates

Hi!

How can I solve this?

+- 01.blog (=> blog.html.twig)
|
+- 02.research
|
+- 03.publications (=> publications.html.twig)

01.blog and 03.publications are both listing pages. For 01.blog I want to use the standard Antimatter blog.html.twig template. For 03.publications I want to use a modified template. Where do I set the option to advice Grav to apply the adapted template publications.html.twig to 03.publications?

Figured it out:

Rename 03.publications/blog.ml to 03.publications/publications.ml

Correct!
