Copying inline formatting to another segment

Our Marketing team is highlighting any changes or new strings in their InDesign file in a certain colour, so that it's easier to identify anything new/changed.
This colour is then also visible in the Trados Online Editor making it easy to see.

However, as it's always the case sometimes you need to make changes to already existing strings and we want to highlight those changes we make at the translation stage, so that Marketing can easily see the changes that we have made to already existing text.

Is it somehow possible to Copy the colour formatting from one segment to another?
Or can we actually set up Trados team, so that we would have a formatting that we can apply to our files, which also gets exported back into the IDML?

Thanks for your help.
