Adding a custom JavaScript (cookieyes banner) to *all* <head> of all pages

Hi,

Is there a way, maybe a plugin slot that I missed, to add something to the <head>section of every pages ?

The context is that I need to add a <script …> tag that points to our cookieyes.com cookie banner on all pages.

It would be nice if there was a plugin slot to modify the <head>section of pages, but I can’t find one. The only solution I found is to fork every single frontend-app repository and edit the public/index.hml file.
