[Geschlossen] URL Paths should remain the same

Background of the issue:
I am trying to maintain the same URL path structure for my pages because I use GoogleTagManager URL Paths for conversion tracking of paid ads. My German (default language) path is: /product/sales/checkout, and I need my translated English paths to look like this: /en/product/sales/checkout. I need to do this manually because my WordPress installation is large with many A/B test sites that must not be translated.

Symptoms:
I need guidance on how to maintain URL path structures during the automated translation process for selected translated pages in WPML without translating the entire installation in bulk.

Questions:
Which settings in WPML should I use to maintain the URL path structure?
What is the process for translating pages manually, such as translating parent pages first, etc.?
