How to remark the text form export target file?

Hello,

I'm use Bilingual Excel with SDL Trados Studio 2017 and I want to remark the translated text in export target excel.

For Example:

source target
English 01 Chinese 01
English 02 Chinese 02
English 03  
English 04  
English 05 Chinese 05

I want Chinese 01 Chinese 02 Chinese 05 in red color or other mark styles.

Does anyone knows how to do with it?

Thanks!
