Thank you, Tuanphan.
That is a great solution. However, it didn't work for the Project pages, unfortunately, as those for whatever reason don’t offer an individual code injection field for each page, only for the main page (equivalent would be you can only redirect the whole blog instead of individual posts). Why they do that is beyond me but I appreciate the effort. Seems that there is no solution to the issue at the moment.
Thank you again.
Best,
Jan
