Composer repository/registry without specifying owner in URL

https://docs.gitea.com/usage/packages/composer

Based on docs, the required URL to use Gitea as a composer repository looks like this https://gitea.example.com/api/packages/{owner}/composer

Is there a way to specify gitea as the composer repository without having to specify a owner?

Something like https://gitea.example.com/composer would be great

From what I understand, composer looks for packages.json at the URL, i.e. https://gitea.example.com/composer/packages.json, see Repositories - Composer

Needing the owner means I need to specify several URLs in composer.json instead of just 1
