Translating a certain language in a multilingual word file?

Hello, I have received a word file that contains the same text in two languages (Spanish and English). I will translate only the English text. 

The file is quite long and includes figures that are also commented in both languages. Is there any "automatic" way to exclude/filter the Spanish text in Trados or before importing the file in Trados, so that only the English text is left (1) to get a precise analysis and (2) to ease the translation?

Thanks a lot in advance for your support
