As already mentioned, there's unfortunately not going to be a good way to scope the text keys themselves unless you have custom pages for all the relevant pages.
The only other option that comes to mind is using JavaScript to set the document.title variable after the page loads. The thing to keep in mind with this approach is that while it may change the title in the end-user's browser, it will likely not be picked up by search crawlers. So it will have little to no impact on what is indexed and appears in search engines.
Hi AdamN ,
Indeed it was for a SEO purpose.
I've filed a support case and NoamanA is trying to find a way to achieve this customization.
As for now we have explored the option of creating a custom page and then override the default page with it in order to be able to create a custom text keys.
Best,
Clement
