Problems with word count for files that only require partial translation

Hi friends

We receive long Word documents from a client in which they indicate text to be translated on a grey background which they format in the original Word document.

Given that it would take us so much time to edit the Word document to remove all the non-grey text, we upload the entire document and then just translate the segments with a grey background.

The problem arises when we have to do the source language word count, as Studio obviously counts both grey and non-grey text.

Is there any way that we can adjust the word count so that it only takes into account certain formats or segments?

If not, is there a more efficient way that we could be managing this?

Thanks ever so much in advance for your help.

David
