"Copy source to target" erases tracked changes

Question

When I edit a Word file that *already* has tracked changes, I want those tracked changes to **remain marked** in the final file -- any changes that I make will be a second layer of tracked changes.

But the default setting in Trados (on my version, at least) is that whenever I select "Copy source to target", the program automatically accepts any tracked changes, and they no longer show up in the exported file.

I don't see where to control this feature in the settings.

How do I keep the previous layer of tracked changes?

In case it's relevant, my Trados version is Trados Studio 2022 SR2 - 17.2.9.18688, and my OS is Windows 10.

 What do you mean by this?

 Normally the target is the translation of the source. So when you open a file with Tracked Changes you can display these changes in the source so they are visible but you cannot transfer them to the target. The only way to manage this is to translate the file as if the original before tracked changes is translated, then turn on tracked changes and make the changes. 
 I think translating an unfinished document is uncommon. Most workflows normally make sure the document being translated is complete and approved before creating translations into multiple languages, otherwise you could end up having to change them all.

 As I said... Trados is a translation tool. The appropriate process is to translate approved documents, not unapproved documents. If you had a multilingual project that went into 40 languages and the source was unapproved, then once it was approved you would have to change all 40 translations.

 ok - in Trados this task would normally be done on the bilingual file in Trados. You open it for review and tracked changes are already on. Every change you make is tracked so someone can proof your work and generate the finished targets. 
 It sounds as though you are taking a translated target files, and translating it into the same language in Trados just to proof it. I can't think why else you would be copying source to target and being concerned that track changes were lost. In this case why don't you just proof it in the final format if you don't have a bilingual file? Maybe you are using Trados for something it was never intended to be used for? 
 Maybe I'm completely misunderstanding you!!!
