How to lock segments based on highlighted text?

Hi everyone,

I was wondering if it was possible to lock all segments that contain highlighted text (or the opposite, lock everything that is not highlighted)?

I have a client who sends me hundreds of pages containing tables with two colums, and I only need to translate one of the columns. I would like to lock the other column, and the only thing I have thought of is to highlight one column in my Word document, and then lock all the highlighted segments in my SDL project. 

However this takes a lot of time to do it manually (as it's not only one big table with two columns, it's hundreds of small tables of a few lines each). I do not think there is a way to filter segments based on the text (highlighted/not highlighted) but maybe I have missed something?

Thank you for any help you can give me :)
