QUESTION How to alter urls and title ?

[morvy]

Yes, I need to change title (and <title> tag) in every generated page. Content comes from json files updated by cron every 12 hours (in real, it updates records once in a week maybe), so everything is basically outside of GS, only "catalog" page is there as a placeholder with metadata and for custom template file if needed.

I tried to use index-pretemplate, content-top hooks but nothing changed, content filter works fine for displaying data in page content, but there is no filter for titles in 3.3
